Met a recruiter at a career fair and was invited for an interview. The interview was about 2 hours away for me and when I got there I interviewed with 3 different employees. They did not have an HR department so I was handed off to people in different departments. I thought the interviews went very well, the questions weren't difficult, and it felt more like just having a conversation with each person. When I asked when I should be hearing back, no one really knew for sure but I was told I would hear back from them regardless of if I got a job offer. I sent a follow up to each interviewer a few weeks later after not hearing anything back. Never got a response to my emails at all. It seems very unprofessional on their part. Especially since they all knew I was traveling far for the interview. I feel like the least they could have done was reply to my follow up.
