As a bright young person, expect your ample potential to be put to use for the financial benefit of the company. You will learn to be a good white collar worker. You'll be compared closely to your colleagues and gently guilted when your metrics aren't competitive. Unless you're a machine or a workaholic, you'll need to set boundaries before this job drives your stress levels off the charts.
-GLG makes money by helping their clients make more money, essentially. Not the most inspiring work. Many employees are jaded.
-Not a very creative or interesting job
-Very demanding, makes work/life balance difficult. Expect to work minimum 50-60hrs per week, weekends.
-High stress. You must be willing and able to manage this. Not one single colleague I knew was not perpetually stressed by work.
-The above results in employee retention problems. HR sincerely wants to change that, most likely to continue to attract high performers.
-Relentless focus on metrics, competitive
-There isn't much diversity in the employee pool.
-Many people who work there are there for the money, so they can be materialistic and very vanilla. They may care more about their bonuses than they care about you. Don't take it personally. The more colleagues you get to know the more likely you'll be to meet a good one.
-Repetitive job tasks can be quite boring and unchallenging once you get the hang of them.
-Eerie cog in the machine feel
-Insufficient training/support around the metrics tools and anything learned past the initial job training
-Self-congratulatory, corny vibes in initial training
