1st round - HR -> 30mins- Very genuine and straight forward questions about resume, work experience and brief discussion on BTA role/interview process. Amazing HR. 2nd round- Case study -> 45mins- Interviewer gave a case study on sales data ( DB questions- indexing, characterizing etc). they are very concerned about wrapping up the interview in exact 30mins. Amazing interviewer 3rd round- Behavioral interview -> Interviewer had an heavy accent, and was so nervous that interviewer literally stammered while asking questions. It made me so uncomfortable, and sort of threw me off. It did not go well. When I finished talking or stopped to see if we were on same page, there were awkward silences. It was so weird. Worst behavioral interviewer ever! I have done well in all my behavioral interviews including McKinsey. Interviewer asked me basic quests like tell me abt ur leadership skills, talk abt team work, how do u manage a project downtime, etc. Again, interviewer cut off exactly at 29:59 mins (LOL). I saw it on my phone. BTW- this interviewer also checked my linked profile ;) I did not make it to the 4th round cuz of what I believe the behavioral interview, although, the HR said I needed more technical skills. I did excellent in my technical interview and answered all questions correctly. The 2nd round interviewer was so happy with me.
