13 Resources for technical interview preparation

I am writing this page as a personal reminder for myself on various interview resources I came across over the internet during the course of my technical interview preparation. There are number of companies conducting a wide variety of different type of interviews, making it difficult to find all resources at a single location. My intention is to maintain a curated list of the resources categorizing them as needed. I hope this list and these resources are helpful to you in crushing your next interview.

  • Coding Interview University


A complete computer science study plan – originally created as a short to-do list for self study. The list of topics is really huge and some of the items may not be even required today, but they are still provided in case you need to refer them. This is like a base course that you need to take before appearing for the interviews in tech giant (like Facebook, Google, Amazon etc.)

  • OG AWS


This is a practical guide on Amazon Web Services(AWS) topics. It got conceptualized from discussion and editing by several engineers who have used AWS extensively. The contents are brief, practical and current and partial in details, for in depth study of the core services covered, you might still need to refer to AWS official documentation.

  • Tech Interview Handbook


This is a “zero to hero” handbook to assist you in your technical interview preparation. It contains number of interview questions, cheatsheets, practical tips. This even contains post interview steps like understanding your compensation and negotiation – overall a complete guide to start your preparation.
