Pros
On-the-job training, no previous collections experience necessary.
Conserve pays for single-coverage for healthcare, and you only paid the difference between single and family.
Bonus potential. You can make very good money with the bonus income here.
Corporate culture and rewarding all of its employees regularly (catering, free sports tickets, annual picnic, winter gala, etc.).
Good 401k investment & profit sharing. My 401k was in stocks with no loss during my employment, only gain. Profit sharing was annual and based on prior performance.
Cons
Greed is rampant and encouraged.
Bonus requirements seemed to increase every year and became more and more impossible.
Team managers play favorites.
Constant office drama.
Poor personal behavior overlooked for high performers (harassment in particular).
