Not at all -- entirely the opposite.
Samwer is a high-pressure boss, well known for treating his reports and employees with belligerence and hostility. That attitude trickles down to the leaders he places in his shell companies. Rocket-family companies demand the long hours commensurate with typical SV startups, but pay developers below-market salaries, and provide negligible to no equity. They're notorious for shoveling a lot of core business work onto a huge, rotating cast of systemically-underpaid interns. I won't get started on the state of their (universal, mandatory) tech stack.
It's actually an adage among devs in Berlin: to studiously avoid anything in the Rocket universe.
