I went through three technical rounds after an initial call with the HR. Despite multiple follow-ups with the HR, I have yet to receive any feedback, positive or negative.

During the interviews, the interviewers would give me a problem and then leave the room. I found it unprofessional and perplexing that they were so busy, especially since they were there to interview candidates.

Looks like they just take interviews for formality.

They took 3 rounds in first round most of things related to C++ and design

Im second round data structure specific questions and in third round again it's on my resume skills and string program and C++
