Do not join unless you're an engineer. You will be set up for failure.
Pros
Great product! Free food, dinner and weekly happy hour. Nice office location. Pretty much it stops there.
Cons
Lack of leadership and management is a mess. Long daily hours and weekends. No work life balance at all and lack of support from managers. There is no professional with other department. Sales, finance and CS team is a mess. There is no support with other department but mostly the blame game. There is a huge lack of corporate processes which should be consistence, effective, accuracy and timely. Everything is manual and pretty much broken. I was trained to email Sales and Finance and just wait for something to happen. It's a black-hole because I am constantly not meeting my client's request and target due to others delay action. Making it impossible to build new or retain client relations. It was a dead end place for me.
