Pros
Lip service works salary (if you can negotiate at every possible opportunity)
Cons
No Cons if you master the above. You need not work beyond above. There is not much new stuff of innovation for engineers happening anyways. You need to crack the code of entering into inner circle of Co-Founders. I had joined thinking that this is engineering company but this is not true. Not much innovation is happening, most of the time its fixing bugs and maintaining status quo on age old stack. It is still possible for you to be happy here. To succeed, you can say yes to whatever Co-Founders propose, make them look holier than thou and take blames in front of people for their mistakes and whims, you are a rockstar. Never ask questions or challenge them, you will be showered with money, appreciation, you can get away with mistakes. On top of it, if you bring them information of what is happening around in the office and become their informer, you will be top performer in the company. This place is not for performers. If you are not in the inner circle, you will be rated below, given small increments. Your smallest mistake will be amplified (courtesy - yes mens/womens), you will be ignored, your good work will be brushed aside. You are on your way out. Better leave now, then. Like me.
