Pros

Pace of work generally pales in comparison to that of big tech

Cons

Recently Mutli year optimization (MYO) was announced by leaders in the US. Massive layoffs followed suit, with long serving employees being let go. Culture was great till MYO started. Everyone's trying to get a slice of the pie right now, in fear of being optimized next.
