It was a behavior type interview. The interviewer was pretty nice and explained his daily routine at work. However, the information he gave me was not sufficient. He was a software engineer and he is interviewing for mechanical engineer position. All the questions I asked him, he answer “I do not know.” He gave me his email and told me feel free to reach out after the interview. I emailed him but he does not even know anything about the interview process. He referred me to other person but the other person did not replied back at all. It was a bad experience for me and would not like to have more interview with them.
