Recruiter contacted me asking to interview with the customer service manager. I was given a hour and a half notice on a Friday afternoon. The interview lasted less than five minutes. The interviewer seemed to be in a very bad mood. When I contacted the recruiter after the interview, they even concurred he seemed to be in a bad mood and the interview should have been scheduled for the following Monday. My overall opinion, this was very unprofessional and I would never consider working for HFT.
