I interviewed at one place where the manager who was supposed to see me turned up an hour late, sweaty from a cycle ride and said I was too early. He consistently got my name wrong during the remaining half hour, and poured scorn on his current reports.

- If during the interview, they ask you if you have 'firing skills' and how you motivate unmotivated staff, that's a strong indicator also. The company was based 20 seconds from the edge of a airport runway. Repeatedly during the interview, we had to stop talking as the noise from jet engines wouldn't allow normal conversation.
