I was interviewed for a senior position and one of the interviewers was smirking all the time, although nothing funny was being sad. The other interviewer had a blank/sad face, not much facial expression.As the last question, the smirking interviewer asked me if I considered myself junior or senior. I thought that was an odd question and I admitted I didn't know everything in the world but I'd still rank myself senior.I don't know, it left a bad taste in my mouth. I'm not used to interviewing people so my first thoughts were 1) they didn't like me and 2) they thought I was wasting their time.I have other interviews this week and I'm trying to not let this experience get into my head. Any advice is welcome.
