I had a very similar, negative experience as one posted here from May 2021. I arrived 10 minutes early for my interview, was greeted and asked to wait in the kitchen while the interviewer finished up.
While I waited, they had me fill out a paper application that looked like it had been created in Word in 1998. This was a pretty good representation of the rest of the office space, which had probably been built out and not updated since 1998 either. Ceiling tiles were rotting/mildewy, junk everywhere, etc.
15 minutes past my interview time, I get to watch them stick with the 1998 theme whenever one of their sales reps rang a bell upon a successful sale.
Finally about 30 minutes after my scheduled start time, the main interviewer is still running behind, so someone else who isn't even in that department is going to interview me.
The first question is "are you able to work 10-7?" Imagine my surprise when the person that initially called me (the owner) never mentioned irregular hours, nor did the job posting.
They really didn't have any more questions for me, and when I pressed him about the operations of the sales team (how many people, average rep performance, KPIs/quotas, goals, commission, etc), he couldn't or wouldn't answer any of them, just kept deflecting.
If the interview was any reflection of how their company operates, stay far away! I'm guessing they try to get away with underpaying and overworking their salespeople if they had to dance around hours and metrics.
