Optiver reviews

Bullying from management and the company does nothing about it despite being aware of the numerous problems. Long hours and demands things get done very fast (sometimes 12+ hours per day). Messy undocumented legacy code and nobody in the organization seems to even know the business requirements it solves so it's nearly impossible to rewrite. Extremely poor code quality (e.g. things checked into code that should be in the database or at the very least in a config, more layers of abstraction than needed, not adhering to best practices, etc.). Very poor culture. Colleagues are obsessed with money. Seriously all they talk about is work and money. Yes I like money too but there's more to life than money. You effectively can’t trade the stock market with personal funds as long as you’re an employee due to huge restrictions they place on you being able to trade with personal funds.

Long hours, terrible work/life balance, lack of support for new hires, lofty expectations without effectively communicating how those can be met.
