Waste of time. HR is poor in responding to calls and emails. One of the worst HR experience ever had in my lifetime. After every round HR do not respond to calls for 2-3 days. When they want us to attend they keep on calling from multiple numbers. After attending 4-5 rounds of interviews and investing 5-6 hours of time in attending all interviews, they say feedback is positive and collect all the documents, they say will not be able to match current ctc, 1. why dont you evaluate at the first place itself? 2. Before attending interviews HR only says the expected ctc is possible, but post interviews it changes? 3. Why such false commitments?

A couple of medium level leetcode questions. 2 system design rounds, each with a higher level engineer. The leetcode questions went for basic stack and tree DS only. The system design rounds were for log system.
