Pros
Some groups are more shielded from the overall company and leadership issues. Also ability to work remote.
Cons
Huge turnover problem. Every year about 40% of the execs leave. Most of that is because the CEO is difficult to work with and extremely unpopular (see articles about him hoarding equity if you want more details). Toptal likes to hype itself up as a company that's "changing the future of work" but in reality it's just a typical staffing agency acting as a middle man. There's nothing game changing here so don't be fooled into thinking this is some amazing tech company. If you join, expect to spend needlessly long hours on completely unimportant tasks. Also don't be tricked by the "unlimited vacation" policy. It's far from that. There's actually literally no official company holidays. You have to request days off even for New Years, Thanksgiving, and Christmas.
