had an interview at a place that went good at the technical part but I didn't do great at their 'abstract' questions. the guys interviewing were complete stone faced as well, no personality, pretty sure I wouldn't have liked working there anyways. a few years later and they are still looking for people. the recruiter rings up and I said I wouldn't want to re-interview unless the process had changed. he guaranteed me it had. so I went back in and it was exactly the same. exactly the same technical questions, followed by more abstract questions. different guys but same no-personalities. never going back
