The interviewer seemed to have a solid technical background.

The company's office seemed reasonably well arranged.

During the interview, the interviewer kept saying that they really liked my experience and hands-on work, and told me they would notify me about the next steps in a week. However, I never heard back. After making several phone calls, sending an email, and calling the interviewer's mobile phone, I was told that they were on a business trip and would reply by email. The reply said that there were other candidates, but two or three days later, the same position appeared again. It felt like the whole process was just using the interview to learn from me.
