If you have any prior work experience, I strongly discourage you from taking a role at GLG, which is sad because I believe the business would be more infinitely more balanced and healthier if they actually had a true middle management layer. Very rarely do they hire anyone as a manager, so despite leadership experience, you will start at level 1 with all the undergraduates.
Intellectually satisfying for approximately 3 months. You can learn to do these tasks, even in "Research," without applying creativity or ingenuity. This is a highly transactional environment. You need less time to think, more time to execute.
They are really trying to elevate what they "do" as a business, but at the end of the day, the bread and butter product is a brief phone call between "experts" and the clients. Clients sometimes care about the GLG employees, but I found they rarely cared about the professional consultants. Total lack of respect for the professional's time, schedule, boundaries, etc. I also found the longer the tenure, the more inconsiderate GLGers became towards Council Members.
Run predominately by 23-25 year old egomaniacs. There is a major sense of superiority among the different financial services teams as well.
There are people in upper management who have been there for too long and who everyone acknowledges thwart progress and satisfaction among employees.
There are an abundance of meetings. Less meetings and more time to actually work and leave at a decent hour would be encouraged.
Typically inflexible when it comes to working from home (even though vast majority of work doesn't require you to be there).
The hours are absolutely atrocious. If you aren't working all the time, then you aren't an asset to them. They praise work-a-holics.
A lot of disparity depending on which area of the business you support - this goes between businesses (Corporate, Life Sciences, NAFS, PSF) and within the business themselves.
