If you aren't from DE SHAW don't join
Pros
Culture, WFH, policies, Office workspace and food
Cons
Top heavy. Some people came from De Shaw and carry that brand imagine in their attitudes. At the top they play a blame game and give tight deadlines and if not met you'll be abused or fired. There is no job security come at your own risk. They fire you if you don't complete tasks and deadlines. They'll put pressure and make you resign. They have an unlimited sick leave option but if you actually use it you'll be laid off. Working beyond 13-14 hours and on weekdays is common in finance heavy domains. Also id say it's not a great place for female employees as the workload and politics becomes unbearable. You're not forced to work on weekends or late night but if you don't work you'll be humiliated or given more work in a way that you resign.
