There were three rounds: technical, technical, and managerial.

The first two technical rounds were good; simple questions were asked by the interviewer.

The managerial round was all about insulting a candidate's current organization. As per the interviewer, their organization is the best in its industry.

The manager was egoistic and truly believed that someone from another organization knows nothing about technology, and that only those who work under his guidance can achieve success. He was also rude to the HR representative conducting the interview.

Even after clearing all three rounds, they were not ready to negotiate on the salary and discarded the initially agreed-upon salary.

Data structures questions asked in the 2nd round.

Binary tree, binary search tree, time complexity, etc.
