But here’s the problem:

The interview process for data science jobs at top companies is *rigorous* and competitive...

Most top companies have at least 3 rounds of interviews, including...

  • 1

    Round #1 - Initial Phone Screen

    Typically an interview with HR, but you could be asked data science & machine learning concept questions.

  • 2

    Round #2 - Take-Home Challenge

    Take-home data science challenge that has multiple objectives and must be completed within a given time limit.

  • 3

    Round #3 - Onsite "Super Day"

    A series of analytical case questions, SQL coding puzzles, technical questions, and even a behavioral interview.

So how can you make sure you’re fully prepared for this rigorous process?

We've got you covered with the Data Science Interview Prep Kit...

Here’s What People Are Saying About EliteDataScience…

This Interview Prep Kit is brand new, but here are some student reviews from our popular Machine Learning Masterclass!

Zachary Washam Investment Banking Analyst, USA

"Differentiator in my day job"

The course has been great. Very well put together, easy to follow, and I feel like I'm learning effectively. I like that it's very interactive - learn by doing rather than lectures. The course has exposed me to things I would not learn in my job but are highly relevant to the analysis I do every day. The things I've learned in this course have been a differentiator for me in my day job.

Julie Truong Marketing Analytics, UK

"Thank you for being human and old school"

I appreciated that 'me' is the most important subject here, as opposed to trying to sell me something all the time e.g. extra resources. I miss the world where companies would go above and beyond to help individuals succeed and let word of mouth do its job, and not try to get a few extra dollars for something really beneficial. Thank you for being human and old school!

Rafael Paim Financial Analyst, Portugal

"Link between the concepts and the real steps of a data science job"

I was looking for the link between the concepts and the real steps of a data science job. The way you approach the models/techniques is a far better way than long and exhaustive statistical explanations. I feel motivated to keep learning more detailed and complex models. This is the "easy and soft" way we can learn and start understanding and apply data science in our day to day problems. I'm very pleased and you fulfill 100% the objective.

Jess Stahl Professor, USA

"The really valuable skill in the near future"

ML is generally presented as though advanced level math is required. Yet, I knew IT and CS professionals who used tools to engage in ML that did not have an extremely advanced math background. This type of course is helpful for those with IT/analyst background who are not looking to invest several years in math courses, but would like to engage in ML. Soon, I think there will be many tools that perform the math so that the really valuable skill in the near future will actually be understanding the process and the results for informed decisions/conclusions/recommendations.

Ben Wilson BI Analyst, USA

"I'm confident to take on predictive analytics projects at the office"

This is at least my 5th pass at learning this material (Thinkful bootcamp, Andrew Ng Course, Data Camp, and a multitude of books). You've given me a rock solid framework. Walking through the full process from data exploration to proper test splits and hyperparameter search to fit the best model was so valuable. A lot of other programs just focus on the algorithm implementation. It's easy when you are starting with the ABT. Now I'm confident to take on predictive analytics projects at the office that no one has had the expertise to tackle before.
