Pros
Design and product teams are very talented and focused on building user centrist products. There's definitely intensity but stems from people being quite passionate about what they build and scoping it so it quite well not building 1000 half assed things that users will find distracting. Think the team balances principled-thinking + new concepts well while making sure we're always worrying how the user would actually use the product, ranging across mobile, web, and browser. There's a lot of pride and obsession, which is contagious.
Cons
The intensity and speed of the landscape leads to fire drills. We have to ship fast bc if we take too long, maybe priorities change and we move to something else. Because of that, we don't get the weeks and weeks at large tech companies to design something perfectly. Think it might rub some perfectionists the wrong way but it's how the world works. Team lunches and dinners ensures we meet other people and bond. Not for the faint of heart aka if you like 6 hours/day, likely not your cup of tea.
