NOTE: there are a lot of companies that do NOT ask leetcode questions. There are many paths to become an MLE, you can create your own path if you feel like leetcoding is a waste of time.

I use LC time tracking to keep track of how many times I solves a question and how long I spent each time. Once I finish non-trivial medium LC questions 3 times, I have absolutely no issues solving them in actual interviews (sometimes within 8-10 minutes). It makes a big difference.
Leetcode questions by categories
- Know SQL join: self join, inner, left, right etc.
- Use hackerrank to practice SQL.
- Revise/Learn SQL Window Functions: window functions

I really found the quizzes very helpful for testing my ML understanding. Also, the resources shared helped me a lot for revising concepts for my interview preparation. This course will definitely help engineers crack Machine Learning Engineering and Data Science interviews.
- K, Facebook MLE
I really like what you've built, it'll help a lot of engineers.
- D, NVIDIA DS
I have been using your github repo to prep for my interviews and got an offer with NVIDIA with their data science team. Thanks again for your help!
- A, Booking
Woow this is very useful summaries, so nice.
- H, Microsoft
That's incredible!
- V, Intel
The repo is extremely cohesive! Thanks again.

This repo is written based on REAL interview questions from big companies and the study materials are based on legit experts i.e Andrew Ng, Yoshua Bengio etc.
-
I have 6 YOE in Machine Learning and have interviewed more than dozen big companies. This is the minimum viable study plan that covers all actual interview questions from Facebook, Amazon, Apple, Google, MS, SnapChat, Linkedin etc.
