Regular Warmup

Final Review

This section will have shorter videos that you can watch pretty quickly to review most of the important concepts.
It's nice if you want a refresher often.

• Series of 2-3 minutes short subject videos (23 videos)

• Sedgewick Videos - Algorithms I

• Sedgewick Videos - Algorithms II

Coding Question Practice

Now that you know all the computer science topics above, it's time to practice answering coding problems.

Coding question practice is not about memorizing answers to programming problems.

Why you need to practice doing programming problems:

• Problem recognition, and where the right data structures and algorithms fit in

• Gathering requirements for the problem

• Talking your way through the problem like you will in the interview

• Coding on a whiteboard or paper, not a computer

• Coming up with time and space complexity for your solutions

• Testing your solutions

There is a great intro for methodical, communicative problem solving in an interview. You'll get this from the programming interview books too, but I found this outstanding: Algorithm design canvas

Supplemental:

• Mathematics for Topcoders

• Dynamic Programming – From Novice to Advanced

• MIT Interview Materials

• Exercises for getting better at a given language

Read and Do Programming Problems (in this order):

• Programming Interviews Exposed: Coding Your Way Through the Interview, 4th Edition

  • answers in C, C++ and Java

• Cracking the Coding Interview, 6th Edition

  • answers in Java

Coding exercises/challenges

Once you've learned your brains out, put those brains to work. Take coding challenges every day, as many as you can.

• How to Find a Solution

• How to Dissect a Topcoder Problem Statement

Coding Interview Question Videos:

• IDeserve (88 videos)

• Tushar Roy (5 playlists)

  • Super for walkthroughs of problem solutions

• Nick White - LeetCode Solutions (187 Videos)

  • Good explanations of solution and the code

  • You can watch several in a short time

• FisherCoder - LeetCode Solutions

Challenge sites:

• LeetCode

  • My favorite coding problem site. It's worth the subscription money for the 1-2 months you'll likely be preparing

  • LeetCode solutions from FisherCoder

  • See Nick White Videos above for short code-throughs

• HackerRank

• TopCoder

• InterviewCake

• Geeks for Geeks

• InterviewBit

• Project Euler (math-focused)

• Code Exercises

Language-learning sites, with challenges:

• Codewars

• Codility

• HackerEarth

• Sphere Online Judge (spoj)

• Codechef

• Codeforces

Challenge repos:

• Interactive Coding Interview Challenges in Python

Mock Interviews:

• Gainlo.co: Mock interviewers from big companies - I used this and it helped me relax for the phone screen and on-site interview

• Pramp: Mock interviews from/with peers - peer-to-peer model of practice interviews

• Refdash: Mock interviews and expedited interviews - also help candidates fast track by skipping multiple interviews with tech companies

• interviewing.io: Practice mock interview with senior engineers - anonymous algorithmic/systems design interviews with senior engineers from FAANG anonymously.
