I had interview for a position with a small managed IT company. It was recommended to me by a friend, but he didn't really know the details of what they did. The job posting was rather vague and focused on the technologies the candidates should know.

In the interview I eventually asked, "what exactly is the goal of what we do here?" one of the interviewers replied "get tickets closed". I think he was trying to be funny. Honestly the fact that I would have to report to him and he can't explain something simple like that was a deciding factor in me declining the job offer. I guess I should've tried asking again.

I asked if there was a list of products we supported. I was told no, but most would be available on a Google search. This too was rather vague.

Am I jumping to conclusions in thinking that these people would be difficult to work with since they can't explain things? In interviews are there other questions I can try asking to get a better sense of what the work is actually doing? I could have tried contacting them the next day and asking "I'm still a bit unclear what I would be doing in this role. Can you give anymore details?" (maybe the second time they wouldn't answer "what our clients want").
