There are five rounds in the process.
First round and Second round: Technical questions and projects discussion
Third round: Managerial Round but still focusing on the technical part
Fourth Round: Interview with Senior lead
This also is technical but their head is such an unprofessional guy, he has least interest in what you are answering. He was having his breakfast/lunch while interviewing me and the sound of crunching was also clearing understandable. He is least bothered with your approach. I was asked to explain about my projects and when I started, within 30s, he asked me to start solving a problem without giving me a chance to complete my sentence. He asked me to solve it using Hadoop MR framework but I was more comfortable on using spark functions to solve the problem. I started explaining it out but he was only looking for Hadoop MR and ended the interview abruptly.
This is such a horrible experience.
