Pros
Autonomy, to an unusually high degree for a HF at this scale. You will not be held back by fixed rules. High willingness to invest in employees, high resources for research and bespoke tech. Far more collegiate than pod shops, kinder culture also (although still a performance culture at the end of the day). Little to no BS. Few recurring meetings, limited red tape and bureaucracy. This allows me to spend 95% of my time and focus on core work. Beautiful office and broader estate with valuable and convenient perks (free meals and coffee onsite, gym and inclusive PT) . These are surprisingly helpful when busy with work. Fast progression for teams that deliver, aided by the high AUM and appetite to take on new managers. The founders are both still around, highly engaged, and are accessible. Extremely rare for a firm of this scale and only possible because of the (relatively) lower headcount.
Cons
Your overall experience will be highly PM dependent (can be a positive or negative, but true for any multi manager). Fast rate of change can take some getting used to, will suit some better than others. Some minor issues with operational business functions from time-to-time
