Before I went back to school and got my CS degree, I worked customer service at a major wireless carrier. At the time (mid/late nineties) they were expanding and growing. I had a friend who worked customer service there (because she wanted to get into sales, and they said 'you will need to get your foot in the door') and said if you can do your year, within six months afterward if you have any skill whatsoever you'd find a different job. She did; I did; it all worked out. We knew what we were getting into and, yes, a year on the phones kinda sucked. I had my eye on a larger prize and knew my own skills, so it worked for me. The woman complains about this, but knew it going into it. I don't know if Yelp *actually* promotes from within, and if they don't this is indeed a specious practice. If they do promote from within (as my previous employer did), then I don't have a problem with it if they disclose up front.
