Pros
1) Clients are major/big firms. 2) Promotions usually occur in time if the performance is good. 3) Good people to work with.
Cons
1) Staffing - From day one you get staffed at a client site you would hardly ever get to visit EXL office for anything, its almost non-existent. And once staffed with a client, rotations to other clients is very less common. 2) Individual Performance - Your performance review entirely depends on client feedback since you have virtually no work related connections with the company seniors itself. 3) Expanding Business - New projects sales pitch being done for bad quality assurance work in the name of analytics consulting, majority of the new work is documentation(yes, work includes customizing word fonts, size, charts etc) 4) Finance Department - Expenses are never approved on time, you end up spending/owing $3k-$4k every month to the firm pending usually another month until you get it back. 5) Travel - If you want to flyback to your base location every weekend, have a good reason to get flights every time or else you ll end up staying at the hotel in a remote area(since hotel budget is low).
