When I was finishing my telecommunications engineering degree, my aunt told me that a friend of her had a work offer for me and we arranged a casual interview.
After some small talk, the first thing this dude told me was: "as you have studied telecommunications, you must be interested on selling telecommunication devices right?". It happened to be a pyramidal phone reselling "work" offer.
I have never felt so attacked. My family thinks I studied 6 years to fucking sell phones.
