I had an interview with SpiroChem and felt the same way as described in other comments. It's a shame because the company's work is truly interesting and there are some excellent professionals, but the interviewer's attitude is terrible. It gives a very poor impression of the company, with such arrogance and complete lack of interest in the candidate. It feels more like a university exam than a job interview. I've done many job interviews, and I've never had such an unpleasant experience. One positive point is that afterwards he did take the time to write to me and let me know I was not moving forward in the selection process.
