Pros
The pay is decent for the role, but the work is monotonous. Responsibility gained in the early part of your career gives you sufficient experience to pivot after the associate role/manager if you know how to sell yourself. The best part of the role is working with people who don't work at AlphaSights (client-facing roles). It is a profitable business for the most senior employees who got in early. If you are looking now, don't bother. They're likely to sell the business anyway now that they've built out their shiny new platform (btw those expensive sheets of paper they sell "on demand" are written by 22 year olds).
Cons
Managers are tasked with sucking every ounce of productivity out of Associates to the detriment of their own mental health's sake. Manager base pay is far below the industry average for what managers are asked to do. Bonus is capped and although you do all of the work the VP+ are only compensated for credit package increases. VPs are by far the most insecure and incompetent population of people you've ever met. They stayed at AlphaSights because they were too cowardly to commission a new job search at a natural departure point (18 mos + annual reviews thereafter). Suffice it to say bootlicking and limiting your social life for the sake of "client success" are the only routes to the top. The hours are awful and there is a rampant culture of micromanagement and self-serving behavior often to the detriment of direct reports and colleagues. If you're smart enough to work at AlphaSights, please work somewhere else.
