Pros
Overall there are good people at GLG and everyone is pretty smart and interesting.
Cons
The biggest con is commission on sales, which hovers around 5% (and I know someone whose all-in commission is 3%). The incentives are totally mis-aligned and do not drive or motivate people, which is why almost all of the senior sales professionals have left over the past 12-18 months. For example, if you sell a 2-year deal you are only comped on 12 months, which means that despite selling a bigger deal which was almost certainly more complex and took more effort, you're only getting paid as if it were a one-year deal. You'd think management would want to encourage multi-year deals because it's guaranteed revenue and makes the client stickier, but instead they discourage it by only comping you on the first year. Similarly, taking on management responsibilities means you have a higher overall quota (since now your all-in number includes your direct reports) but doesn't include an increase in your comp -- so you have a bigger number to hit and more responsibility for the same money.
