I sat for like an hour waiting for someone to come get me. Then when they did, the person who would be the role’s boss emailed for ten minutes while I sat awkwardly in front of them. Then they asked what I listened to and they told me they weren’t looking for BS.

Extremely unprofessional. Made me wait forever to interview with my potential boss; Sat on his couch while he did work for 30 minutes before asking me any sort of question. Told me he 'had no patience for bs' and that was about it. Second round interview I sat next to someone at their desk and they asked me what music I listened to. Thought it was kind of cool at the time, but having now gone through professional interviews, realize that you can tell a lot about a company by the way they handle this process.
