Pros
Big goal, casual environment, room to try new things. Flat structure. Lots of leisure spaces in the office. Some perks and good work life balance (in term of Hong Kong standard). Works have an audience and direct impact. Good potential if they hired some good middle management.
Cons
Hiring lacked standard, onboarding was chaotic (nobody knew what to do on their first day). Some great people, but also some apathetic teammates. CEO is never around, and no middle management to move things forward. Culture is lacking, and management couldn't band people together. When some employees left to compete with the company and team was destabilised, instead of strengthening culture and management the company went opposite direction to tighten rules, causing more people to leave.
