They are not professional on their interviews, they should have said no from the beginning. The process is long and their expectations on the interviewee are sky high. I considered my interview to be excellent, answering all their questions about team work, personal experiences and analytical skills. There are 5 people interviewing one after the other, and some were nice (3 of them) and the other 2 were not that much. At the end they gave me false hope because they told me: YOU DID AN EXCELLENT INTERVIEW, HOWEVER WE CANNOT OFFER YOU A JOB because basically all of the other candidates did better than you, I mean, what kind of crap is that?? Seriously, I felt like I was the backup in case one of the other candidates didnt accept the offer, that's UNPROFESSIONAL by any means, they should have just told me no and I would have accepted their decision, but the fact that they said that my interview was excellent is what threw me off. DO NOT RECOMMEND.
