Pros
The level of competency of your peers are very high. So there's great opportunity of learning from them. And there's usually an open line of communication, so people share their knowledge openly.
Cons
The culture of the company is to do overtime work. Bosses go home very late (11pm or later) and even work at home and even weekends. Sometimes there's an expectation for the regular employees to do the same. This breeds an attitude of dissatisfaction among the regular employees because mostly of burnout and unbalanced work-life. Since I joined the team 2 years ago more than 10 (experienced and competent) people already left because of the above reason, and our managers doesnt seem ( or dont bother) to understand whats the source of the 'mortality rate' . They just hire new people.
