Pros
Awesome training for people interesting being relatively well paid telemarketers. The business model is refined and analyzed to the gnat's backside, and if you follow the formula you should make decent money in your first year. And if you want a career in sales and have some accounting background, this is an excellent place to make a start and get best-in-class training. if you can manage the stress of the constant threat of discipline for failing to meet one of the conflicting metrics you're subject to, the work life balance is also really good. I made 2-3x the salary of my friends who had regular desk jobs and didn't work nearly as much overtime, hardly any in fact.
Cons
The system is designed so that you will, ultimately, fail. If you make enough phone calls, you weren't out in the field meeting clients...if you met enough clients, you didn't do interviews with potential temps/hires...if you did enough interviews, you didn't close enough deals...if you closed enough deals, you didn't get enough margin on the deals (as defined by the corporate formula, not by current market conditions)...even if you do ALL that and with some luck get some gang-buster clients and are making good money for the company and yourself, management will reshuffle your book of business so you stay hungry. The focus on sales vs. recruitment has been an evolving trend with the company, so where they used to value putting the right people in the right engagements, they now tend to focus on "just fill it and we'll replace the person if it doesn't work out" tactics. There is also a trend to make the top salespeople into Division Directors, but then they just end up competing with their own staff for deals because the extra $ you get as a manager doesn't compensate for the loss in personal productivity.
