I got one of those many years ago when I was in college. I desperately needed money, so I found a job listing on Craigslist, sent my resume, got a call back, we agreed on the in-person time and place, it was neat.

I show up at a building 2 blocks from school, a random tenant tells me to form a line by the door that was locked. I was confused because I was the only one there. A second person came in, joined the line. Then a third, fourth, fifth. We were a crowd, standing in front of a door, where I thought I'd interview for a entry level job in tech.

When the door opened and the person on the other side greeted us and a good number of people immediately left. More luck for me to get this job. But turns out, it was going to be a group interview. In fact, not exactly an interview. It was a pitch. And a few lucky ones would have the privilege to sell high tech knives. All we had to do was buy the first batch of knives for something like $300.
