Pros
On the job training, advancement opportunities, team atmosphere, flexibility and professional growth. I came to TQL straight out of college with zero sales experience, but TQL gave me a shot anyway. Since then I've moved through a few different positions and can say without a doubt, if you work hard and show initiative - you will make it here in one way or another. If you expect ANYTHING to be given to you (here or in this industry) you should look for employment somewhere else. If you have no problem putting in the hours, the effort and the patience it takes, you'll gain more out of the experience than anyone you hear from who "didn't make it."
Cons
Some people expect to come out of college and walk straight into a 45k "desk job" sharing clippings of newspaper cartoons and taking hour lunches. Working at TQL is not that job. You start at the bottom and work to the top. Slackers need not apply.
