Crack the Data Scientist Case Interview by an Ex-Google Data Scientist

[@1220MrCool]

Honestly all of this prep for a single interview is a full-time job itself.

I know the pain, been there multiple times. But hopefully it’s well worth it at the end - Dan

@@DataInterview I will give this a shot for my own practice and benefit. Thank you kindly!

@@DataInterview What is a better way to understand business terminology tied to predictive models for any arbitrary business? I don't have business knowledge to understand the ways to go about these things (lack of business experience while using DS), so how do I learn about them if companies don't release their models?

[@cliffrunner]

it is more. a full-time job doesn't need you to do A/B testing, data ETL, model POC, model serving, and product understanding etc. at the same time

I totally agree that the case study is really tricky. Unless you have encounter similar problems before, ti is very difficult to come up with a good approach in a 15 min timeframe. To be honest, in real work, nobody is gonna ask you to present a solution in mins. Any realistic and practical solution requires days, even months of work. That being said, this type of interview is nothing but a 'leetcode' type of test: find some case study questions (especially for the company you are interviewing with), and practice over and over again. It is easier to prepare for big tech where you can find plenty of questions online that smaller companies.

[@johnxiaoyuzhang9048]

how did it go?

[@ramnapper2010]

The youtube algorithms of July 2023 decided I should view your video....what a great video on concepts, insights, and guidance! I'll check out more of your content.

[@meghhhadas]

Most useful and educative video on problem solving I have seen over the Internet! Thank you.

[@joseharper3314]

How did I not see this before the last 5 case studies I bombed 😢. Ty!! 😊

[@jessyzh917]

Very useful content, and you made it so easy to follow and articulate the main points to keep in mind. Thanks so much Dan.

[@nikhilshingadiya7798]

I want to add in last your case study(driver), sometimes our past data is not enough for churn predication. we needs conduct survey in such way that the we can measure driver actual psychological,physical and financial condition this features(we can use likert scale) will help us to minimise our churn predication.

Thanks a lot! It's very useful!

[@zubrz]

the last answer to Lyft churn problem sounds super evil, mechanistic, treats people as objects, something like from a scenario of Black Mirror

[@horoshuhin]

truly magnificent breakdown. thank you Dan

[@DataInterview]

Awesome, glad you found it helpful! More content like this coming soon!

[@Rameshkumar-zh3jr]

Thank you Dan!!!

[@fahnub]

thanks for this

[@bergkampthagoat]

This seems like an awful lot for an entry level job. Am I correct in thinking so?

[@johnwig285]

Because a data scientist isnt an "entry level" job in reality.
