Pros
My turn soon over here. Had a few good years, the right place right time, with a decent kitchen.
Cons
2018 on record year bonuses were almost flat so management could pay themselves higher. 2019 year was chaos. Profits down dramatically. Greedy mismanagement, no clear direction. Entire firm is just copy + paste of Optiver strategies, which can only take you so far. No new ideas just iterating on the late 2000s. CEO spend half the year distracted by a fumbled deal, then fire the CTO and cause exodus of senior developers (after some of the best senior traders and quants already left). Management generally absent, across the board low understanding of modern technology - probably not a single person in trader management could explain you how to write basic script, yet they try to call the shots for tech directions! Read positive reviews on the glassdoor with salt - many very obvious stink of HR flavors.
