Pros
Best place to be for a Manager - You get to do high level work like enjoy the scenaries outside the window, gossip and have free lunches/parties. Menial work like talent management, performance appraisal, employee engagement are not the focus for them. Flexibility - Not because they care about "your" work-life balance, but don't want to hamper their own Best in class project managers ("Senior Researchers") - They prepare you to face the worst. Puts a lot of emphasis/effort on breaking peer ("Researcher") morale by finding useless/irrelevant mistakes in deliverable, just to show who is the boss. You get to learn how to bloat in your own false sense of achievement from your PMs and Managers Good Pay and hike - for literally doing nothing (and gaining nothing) (Please note: All this benefits is subject to the Research team only, not sure if other teams offer these or not)
Cons
Nothing i can think of, except - You fall into complacency You learn no new skill You start having false sense of achievement You become unemployable after spending a couple of years here
