International Rescue Committee Administration Assistant interview questions

I applied online and a couple days later in the evening received an email asking to come in for an interview the following morning. There were two people interviewing, and when I asked about advancement opportunities at the end of the interview, I was told that there's absolutely no opportunity to progress in your career here. The interviewers were negative and were complaining about how they didn't always enjoy their job and how sometimes they hate coming into work. Poor atmosphere, did not feel welcoming or enticing. I was asked to come in for a second round of interviews, but I did not.
