Pros
I worked at GLG for 3 years and struggle to give a rating (I put 3 stars, but my experience ranges from 2 to 4.5). Couple of factors: a lot depends on the group you work for and the entire company is undergoing a massive transition right now, following the start of the new CEO in March 2018. I had a great experience for about 2-2.5 out of my 3 years with the company. The group I worked with had a good culture. I had great opportunities for interfacing with senior clients, working on a range of projects and had a boss who was supportive of my path to advancement. A lot of company-wide changes were set into motion when the new CEO joined at the start of 2018 and my group's leadership changed the following year. I left because I was no longer aligned with either the business strategy nor the people strategy. PROS: Potentially a quick path to advancement, exposure to senior leaders, range of work
Cons
In the current transition, which has resulted in a mass exodus of GLG-ers across offices / business units, the perception is that there is no focus on people and the overall business has become very transactional vs. client relationship centric
