My 2nd interview with this new company was with my new direct supervisor. We talked for 90 minutes, 10 of that was work related, the other 80 was about cars, which he's into too.Needless to say, this probably helped develop a connection.
The current job, I listed working on cars, and the guy who hired me (now gone) builds rock crawler buggies out of Land Rovers, and is an amateur machinist as a hobby, so that was a good bonding point.
