Their recruiter doesn't know how to ask a question. they are impolite and really rude. They ask you a lot of questions to trick you instead of trying to understand what is your background or even what did you do before. there are only interested in them and also in the company. This is the second time I have had an interview with them and both times when terrible wrong. I decided that not all the recruiters and decided to reply with a different recruiter and I saw the same process after my 2n interview I send an email saying that I don't pursue the interview process with them. be carefull and take time to answer the question really think that their are not a shadow question and they trying to figure out.
