There’s plenty of accurate feedback on what Research is like on Glassdoor (see the most “Helpful” rated comments), but if for some reason you do decide to take a job at GLG, do NOT join Research Operations.
I have experienced more than one role at GLG, and can confidently say that being on Research Operations is the least optimal choice. Don’t get me wrong, GLG as a whole lies to you about your job/day-to-day and completely bait and switches bright-eyed bushy-tailed grads into taking “research roles”, but no role is worse than being an associate on ROps, especially Project Support or Member Solutions. They are incredibly high-volume, transactional, basic admin/customer service jobs, and not a thing more. In fact, management measures your professional worth by the number of emails you send and how many calls you take and schedule in a day.
The turnover on those teams is rampant and for good reason. Like many other reviews accurately claim, GLG is full of awful management, and that includes on Research Operations. Middle management is completely unapproachable when issues arise, are wildly passive-aggressive, and are clique-y, micro-managers who can never accept or take responsibility for their faults.
In general, be apprehensive of anyone who has never been in management outside of GLG.
