Avantages
1. Great Team 2. Great atmosphere 3. Solid sales - by this I mean they will sell you anything but the reality is totally different 4. Great team leads - you can always count on them to help you at least with a piece of advice or guidance 5. You can gain a bit of experience working with teams and using Agile Methodologies
Inconvénients
1. There is no kind of organisation 2. Management does not care about employees and products at all 3. Low wages - one of the lowest I have encountered anywhere 4. Always requiring people to work overtime but you won't be paid for it or get any kind of reward or anything 5. Bad project organisation 6. You don't have a chance to self-develop and they won't give you anything worthy of trying to stay longer time 7. You can't have a different opinion from the management otherwise you can't ask for a bigger salary or you get fired automatically 8. They will often try to make a lot of pressure on employees to work on some brainless tasks or to learn new techniques and work on projects for clients which means clients won't get a good product for their money 9, Missing a lot of people (junior/mid/senior-level devs) instead they hire a lot of practitioners because they get lower salaries etc...
