Somewhat technical - Some interviewers seemed unqualified to interview this position. I was asked several questions concerning my mechanical aptitude - tools, ladders, lifting... I was asked if I had ever worked in a union shop environment.

Interview became a full 8 hour day process which was a pain because all you're guaranteed out if it is some pizza. Didn't get hired on first round but was told I made the hiring pool for their next round. Only took 18 months for them to officially hire me after the interview
