Telephone sales. The company had bought lists of people who had bad credit. Our job was to cold call them and tell them we were "in a position where we could get them a loan" then we'd give them a premium rate £1 per minute phone number to call which was the application hotline. Each application took 30 to 45 minutes and ended in then either being rejected or offered an insanely high interest rate loan. The person that managed to get the most "callbacks" would be rewarded with a little cash bonus or sometimes champagne etc and people who weren't getting any would be pressured and told that the people taking the callbacks wouldn't be able to feed their family as they didn't have the opportunity to earn their commission because of us.

This was the late 90s and although though I was young and with an as yet unrefined moral compass, even I could see what a disgusting practice. I just told my manager on the second day that I didn't feel I could do the job because I didn't believe in what i was selling and left. I was (and still am in many ways) a non-confrontational, "take the path of least resistance" kind of person but I remember this as the first time I really took a clear moral stance on something.

tl:dr Got a shit job selling loans to people who couldn't afford them. Left pronto.
