3 phone screens and one onsite The first call was with the recruiter and that was pleasant enough. The second call was with a technical person who seemed highly competent, asked the right questions and was on top of his game. The third interview was with one of the group leaders and covered lots of ground technically. All seemed to be going well. The forth interview was onsite and with the same group leader from interview three. The office seemed cheerful and pleasant with lots of food out in the kitchen. I was not impressed at all with the group leader during the in-person. His constant use of vulgar language throughout the interview was a huge turn-off for me. I took that as a sign that either he had a lot of angst or repressed energy if he had to turn to swear words to describe his every day life at work/home. However, he did offer to take me out to dinner prior to the start of our interview. Aside from the linguistics anomaly the bent was really towards selling stuff. Given I'm more of a technical person that is not the way to sell me on the job. A huge turnoff for me in general and his spontaneously disclosing that they have a 10-15% technical staff turnover each year was another red flag. At the end of the 3 hour interview there was no closure at all except for a hand shake and that prior offer for dinner just vanished into thin air without even a word. Very strange. Also, absolutely no follow-up from the recruiter at all after setting up the initial phone screen. Another sign for me of incongruity in their internal processes.
