GLG is having an identity crisis at the moment. It's made a name for itself in its ability to connect some of the largest money managers on the planet with the greatest minds in their respective fields. However, the company is currently re-vamping/re-branding/re-organizing and losing touch with itself. The newly completed NY headquarters looks more like an evolving tech start-up than a finance-focused company so if you're looking to stay in the finance space, stay away. They are beautifying themselves to be bought out by a LinkedIn or Google or the like.
However, there is incredible disconnect with those servicing finance firms (Hedge Funds, PE Funds, Banks, etc) and the current endeavors of management. In short, it's turning overwhelmingly unprofessional. To add, those in senior leadership roles have terrible ego issues and do little to help the development of individuals, particularly in the hedge fund sales division.
Lastly, they preach being "Partners" with their clients and working to take market share from the likes of Bain, BCG and McKinsey yet the CEO constantly refers to GLG's "clients" as "customers. He's probably the most glaring concern and hindrance if GLG wants to continue to grow and defend its market share against the up and coming competitors.
