Study guide
LeetCode (not all companies ask Leetcode questions)

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. A better way is to use LeetPlug chrome extension here
Leetcode questions by categories
SQL
Know SQL join: self join, inner, left, right etc.
Use hackerrank to practice SQL.
Revise/Learn SQL Window Functions: window functions

Statistics and probability
The only cheatsheet that you''ll ever need

Learn Bayesian and practice problems in Bayesian
Let A and B be events on the same sample space, with P (A) = 0.6 and P (B) = 0.7. Can these two events be disjoint?
Given that Alice has 2 kids, at least one of which is a girl, what is the probability that both kids are girls? (credit swierdo)
A group of 60 students is randomly split into 3 classes of equal size. All partitions are equally likely. Jack and Jill are two students belonging to that group. What is the probability that Jack and Jill will end up in the same class?
Given an unfair coin with the probability of heads not equal to .5. What algorithm could you use to create a list of random 1s and 0s.

Testimonials
V, Amazon L5 DS
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.
Intro
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.
