Pros
The only plus are the lovely people you'll meet there who have been just as naive and unfortunate as you to join.
Cons
AlphaSights was by far the worst period of my entire life. You innocently think you are joining a 'normal' company with great trajectory but all your drams and hopes are soon to be crushed. I don't need to echo all the other reviews but being an Associate is being nothing else but being a professional harasser and stalker in the most micromanaging and toxic environment you will ever experience. They take intelligent and motivated graduates and brainwash them into thinking this is a normal environment. For perspective: there were four people in my direct team who left for 1 to 2 months to recover their mental health. All of my former teammates are in therapy now to recover from this experience. There is so much more to say but just take this away from reading the post: do not even consider this, please.
