Pros
Great experience for recent grads (B/C schools) who have not figured out what they want with their career, decent client exposure at junior levels, the job is promoted as research associate- in fact you will be a recruiter for 2 years, it's a boring and repetitive job, you will develop soft skills but will be definitely bored after 2-3 months. You will spend 90% of your time searching a database and cold calling/LinkedIn recruiting. Managers are account owners - very repetitive job, decent client exposure, but very superficial contact - you are incentivised to sell services to clients/ upgrade their usage.
Cons
Complete waste of time for people with at least 2-3 years of experience and a good skill set. Very limited career opportunities, very political environment, bad compensation, the work is repetitive, boring and does not require any quant nor research skills. Terrible culture, the management is only interested about cost cutting and does not care about employees' career development/skills set. GLG services are becoming commoditised, no corporate culture- it feels like expensive call center. Do not recommend, it is only suitable for people who have no career aspirations. Employees are disengaged, limited career development opportunities and very high turnover since the new management joined the firm. GLG values are solely related to boosting profits- the company charges clients huge mark-ups without delivering real value.
