- Treasure Data (current): 1.5 hours a week (100 ppl company)

- Oracle (past): 1.5 hours a week (a few thousands ppl)

Both cases my team and management avoided unnecessary meetings, the 1.5h is for two meetings: 1:1 and team meeting. It's not up to the company size, but instead how optimized your team wants to behave.

note: I am in a SW Engineer position. Not sure about Marketing, HR, Finance..etc.
