Google

Contacted by a recruiter on LinkedIn. Went through a phone screen with a rude interviewer. He seemed to be talking down on me from the get-go, likely due to his 5+ years at Google.

The interview process was long, involving 5-6 rounds of interviews. There were numerous technical questions and samples. I met with several members of the hiring team at different stages of the interview process.

It was hard. I was rejected after the first round because I was not prepared for DSA. They asked a mathematics problem and a DP knapsack problem, which I was wildly unprepared for.
