There were 7 rounds, 3 rounds were on DSA and 4 on system design/ general technology questions. it took almost 6 months to complete the 7 rounds.DSA questions where of medium difficulty but they covered all the concepts from arrays, stacks to graphs. Most of the system design questions where based on their tools and product. They asked a lot of questions around the technologies mentioned in the resume. All in all it was medium to hard difficulty. but at the end they just low balled the offer and gave just 3% increment on current package.
