Hi I’m Fahim

As a software engineer at Meta and Microsoft, I helped develop cloud-scale distributed systems, including Azure and Facebook storage.

In my 20+ years in tech, I have also personally led hundreds of System Design Interviews.

These are the resources I wish I could have given to candidates to guide them through the interview process.

The best part — it’s all 100% free.

I hope you find this handbook useful. Good luck with your interviews!
