Pros
Not many... I had "camaraderie" with my teammates which was great. We were in the same mess together.
Cons
TikTok has experienced extraordinary growth in a short period of time. My sense is that they have not hired the right people for the roles they're in and it is a mess - the consistently high attrition reflects this. No clear business strategy, poor leadership, no clear opportunities to develop. Refer to having a "flat structure" but my experience was incredibly hierarchical. No org charts or visible role titles means project work is siloed and clunky, you can never find who you need to speak to and have no visibility outside of your lines of reporting/direct team. I saw on Linkedin some TikTok employees in the same role as me in the same job location but I had never seen/heard of them before! Overall a terrible experience and my mental health has significantly improved in the time since I finished. I acknowledge this may be a different experience outside of the business/team I worked in.
