Heard a story (factual) of Australian trained pilot went overseas and got a big jet F/O job. Returned several years later for an interview with one of the domestic airlines. Interview board was one HR lady and a company pilot. On being introduced, both pilots looked at each other and realised they had learned to fly at the same flying school. To the concern of the interview board pilot, the other guy shook his hand vigorously and gave him a big bear hug with a "Gooday Maaate - haven't seen you for yonks - how yer been?"
Not exactly the way to impress an interview board one would think.. They weren't and the result showed that.
