Data Science Career Guide – Interview Preparation review for 2026

In our review of this course, we try to help you answer all of your most important questions about Data Science Career Guide – Interview Preparation as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use DSCG-IP as an abbreviation of the course name?

During our Data Science Career Guide – Interview Preparation course review, you might sometimes see us refer to it as DSCG-IP for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and DSCG-IP is simpler and easier for reviewing purposes

The full course name is 49 characters long, including blanks, while DSCG-IP is 7 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 42 characters every time we use DSCG-IP.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to DSCG-IP throughout the remainder of this review.

Is the Data Science Career Guide – Interview Preparation course for you?

To determine whether Jose Portilla’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what Jose Portilla’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Jose Portilla chose for the course, “Data Science Career Guide – Interview Preparation”, as well as its subtitle: “Prepare for your Data Science Interview with this full guide on a career in Data Science including practice questions!”.

This combo of title and subtitle should be enough to communicate the purpose of the training if Jose Portilla is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what DSCG-IP is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means Jose Portilla hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Data Science Career Guide – Interview Preparation is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Jose Portilla’s official description of DSCG-IP

According to Glassdoor, a career as a Data Scientist is the best job in America! With an average base salary of over $120,000, not only do Data Scientists earn fantastic compensation, but they also get to work on some of the world’s most interesting problems! Data Scientist positions are also rated as having some of the best work-life balances by Glassdoor. Companies are in dire need of filling out this unique role, and you can use this course to help you rock your Data Scientist Interview!

This course is designed to be the ultimate resource for getting a career as a Data Scientist. We’ll start off with an general overview of the field and discuss multiple career paths, including Product Analyst, Data Engineering, Data Scientist, and many more. You’ll understand the various opportunities available and the best way to pursue each of them. The course touches upon a wide variety of topics, including questions on probability, statistics, machine learning, product metrics, example data sets, A/B testing, market analysis, and much more!

The course will be full of real questions sourced from employees working at some of the world’s top technology companies, including Amazon, Square, Facebook, Google, Microsoft, AirBnb and more!

(Read more about this course on the official course page.)

Does DSCG-IP pass the 30 Seconds Test?

You can read a lot more about Data Science Career Guide – Interview Preparation on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, Jose Portilla has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other Development classes that are more clearly defined and more tailored to your specific interests.

Did Data Science Career Guide – Interview Preparation appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with DSCG-IP above, what is your gut reaction to this Development course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did Jose Portilla do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Jose Portilla’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other Development courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does Jose Portilla sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the DSCG-IP course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Jose Portilla’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including Jose Portilla, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from Jose Portilla’s Udemy bio

Jose Marcial Portilla has a BS and MS in Mechanical Engineering from Santa Clara University and years of experience as a professional instructor and trainer for Data Science and programming. He has publications and patents in various fields such as microfluidics, materials science, and data science technologies. Over the course of his career he has developed a skill set in analyzing data and he hopes to use his experience in teaching and data science to help other people learn the power of programming the ability to analyze data, as well as present the data in clear and beautiful visualizations. Currently he works as the Head of Data Science for Pierian Data Inc. and provides in-person data science and python programming training courses to employees working at top companies, including General Electric, Cigna, The New York Times, Credit Suisse, and many more. Feel free to contact him on LinkedIn for more information on in-person training sessions or group training sessions in Las Vegas, NV.

(Learn more about this instructor on the official course page.)

What did you think about Jose Portilla after reading just the first few lines of the bio above?

After reading just the first few lines about Jose Portilla, did it make you more or less interested in taking the DSCG-IP course?

And did it make you feel like Jose Portilla was more or less credible and qualified to teach Data Science Career Guide – Interview Preparation?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this Development course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the DSCG-IP lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Data Science Career Guide – Interview Preparation course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the DSCG-IP course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing Jose Portilla’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Data Science Career Guide – Interview Preparation, as well as the course’s subtitle, Prepare for your Data Science Interview with this full guide on a career in Data Science including practice questions!.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that DSCG-IP is potentially a good, useful course for you, and you can have more confidence in Jose Portilla’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from Jose Portilla that you enjoyed?

Have you already learned something from Jose Portilla that you valued or enjoyed?

For example, does the Data Science Career Guide – Interview Preparation training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any DSCG-IP lessons for free, have you perhaps watched a YouTube video by Jose Portilla, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Jose Portilla’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Jose Portilla’s teaching methods, and the more you enjoy them, the more likely it is that Data Science Career Guide – Interview Preparation will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Jose Portilla before purchasing this course, since it’s one of the best ways to determine whether DSCG-IP will be helpful for you.)

Are “Data Science Career Guide – Interview Preparation” reviews generally positive?

On the bottom of the DSCG-IP page, you can read student reviews of the class.

Prior to March 14, 2026, there were 4,080 students enrolled, 1,714 reviews / ratings, and it was overall rated 4.5 out of 5.

Obviously, the more highly other students rate DSCG-IP the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the DSCG-IP reviews to get an overall sense of them. You don’t have to read each one!

Is Jose Portilla responsive to student questions in the DSCG-IP training?

You can see what other students have to say about this in their DSCG-IP reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Jose Portilla a message through this system quite easily, even if you haven’t bought DSCG-IP yet.

For example, you could say, “Hi, and I came across DSCG-IP while looking at Development courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Data Science Career Guide – Interview Preparation on your own, online?

This is a big one, because Data Science Career Guide – Interview Preparation is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Data Science Career Guide – Interview Preparation.

Yes, you will be able to interact with the students and the teacher, Jose Portilla, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of DSCG-IP make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Data Science Career Guide – Interview Preparation training that looks something like this:

• The purpose of DSCG-IP can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• Jose Portilla is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other DSCG-IP students have great things to say about the program

Other benefits include:

• You get to go through DSCG-IP at your own pace
• You join a community of 4,080 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that DSCG-IP would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford DSCG-IP?

Can you comfortably afford the cost of Data Science Career Guide – Interview Preparation?

This is an important question to answer, because even if you think DSCG-IP sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before March 14, 2026, the price was $14.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on DSCG-IP with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Data Science Career Guide – Interview Preparation?

By far, the easiest way to get the best and biggest discount on this course is to use the Data Science Career Guide – Interview Preparation discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Jose Portilla’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best DSCG-IP course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting DSCG-IP for a better price, but also with any other Jose Portilla Udemy course that you’d like to get for cheaper.

How can Google help you get a DSCG-IP discount?

To use this method, do a Google search for the DSCG-IP training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Data Science Career Guide – Interview Preparation promo code” or “Data Science Career Guide – Interview Preparation udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with Jose Portilla’s name and see what happens.

For example, you might do a Google search for “Jose Portilla Udemy coupons” or “Jose Portilla course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Data Science Career Guide – Interview Preparation coupons” rather than “Jose Portilla coupons”.

How can a Udemy sale get you DSCG-IP for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get DSCG-IP for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Jose Portilla decides not to participate in the site wide sale, then you won’t get a discount on DSCG-IP, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the DSCG-IP course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a DSCG-IP discount from Jose Portilla?

If you’re really serious about getting “Data Science Career Guide – Interview Preparation” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Jose Portilla, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Jose Portilla’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Data Science Career Guide – Interview Preparation. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Jose Portilla’s mailing list, if you can find it, and then you hope that at some time DSCG-IP will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get DSCG-IP for free?

Of course, the best possible price for the DSCG-IP training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Jose Portilla has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Data Science Career Guide – Interview Preparation free coupon” or “Data Science Career Guide – Interview Preparation 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even Jose Portilla has offered free coupons for DSCG-IP in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a DSCG-IP free download?

It’s important to understand that there’s a difference between getting full access to the DSCG-IP training for free legally with a free coupon code vs. finding a way to download DSCG-IP illegally.

If you really want to go the download route, you can do a google search for something like “Data Science Career Guide – Interview Preparation download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Data Science Career Guide – Interview Preparation free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, Jose Portilla created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 4,080 students enrolled in the program.

Can you get a refund on Data Science Career Guide – Interview Preparation if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the DSCG-IP training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into Jose Portilla’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on DSCG-IP no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the DSCG-IP training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Jose Portilla could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing DSCG-IP and not liking it, since you can always get your money back.

What is OCP’s overall rating of Data Science Career Guide – Interview Preparation?

During this DSCG-IP review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the DSCG-IP training, the instructor, Jose Portilla, and reading what other students have said about this program, we give it an overall rating of 4.8 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.
