Minimum Viable Study Plan for Machine Learning Interview

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 5 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, Intuit etc.

Study guide

LeetCode

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

SQL

Know SQL join: self join, inner, left, right etc.
Use hackerrank to practice SQL.

Programming

Java garbage collection
Python pass-by-object-reference
[Python GIL](Fluent Python, chapter 17](http://index-of.es/Varios-2/Fluent%20Python%20Clear%20Concise%20and%20Effective%20Programming.pdf)
Python multithread
Python concurrency, Fluent Python, chapter 18

Statistics and probability

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?
Alice has 2 kids and one of them is a girl. What is the probability that the other child is also a girl?
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.
