I'm sure this is worse because of WFH but I experienced this at FAANG before WFH. The teams are giant, there's a huge list of things to work on, pick one, do it mostly on your own. Loneliest job I ever had. Yea there were co-workers and we'd get lunch and talk but we weren't collaborating, only co-existing.
Do you mind saying which FAANG you found that environment in?
I can understand why some people wouldn't enjoy that environment but a focused workday then a chatty short lunchtime walk sounds like an enjoyable work environment for people like myself.
