Pros
The tech is really cool. There is lots to learn and definitely lots of opportunity to learn. Benefits are pretty decent and so is pay. Company started offering snacks and partially paid lunches. Also, there is low overhead, so getting work done is easier. You don't have to sit in countless of pointless meetings.
Cons
The biggest downside for me is lack of support. I understand that there is a learning curve and a period of self learning for wherever you work. However, when you get stuck on something and tried everything you could possibly think of, management just hits you with stricter deadlines instead of offering help. When the deadlines didn't improve performance (because I was still stuck), the deadlines became even more strict. Now, I understand that the deadlines are put into place to get the work done, but if you see your developer struggling on a problem, you should think about actually providing some help. For my specific situation (can't say for all other managers), my manager consistently keeps undermining my ideas and makes my try out his ideas. Of course, when I've wasted so much time testing his ideas, I am left with the blame that I couldn't come up with the solution sooner. On the same note, work feels very siloed. Almost every person for themselves. You actually can't get much help if you are stuck on something. Also, the way engineers tackles problems here is to come up with quick fixes rather than solid fixes. So, quantity over quality. They care much more about how many bugs you can fix rather than how difficult the bug fixes are.
