Pros
There are 2 pros: 1. You would get a fantastic experience in dealing with a boss who is unnecessarily hard to work with. 2. Since there isn't any order which is put into place you will be asked to do multiple things at any time out of your purview, Hence you will be forced to get better at multitasking.
Cons
Quite a few cons, but I'll put the ones I remember: 1. No growth. 2. The salary is not concurrent to the type of work which everyone is made to do. 3. People have been unceremoniously let go after they put in a lot of hard work. Once you witness this, you will ask yourself the question of why are working here. 4. Public Holidays don't exist. 5. Higher management takes extra interest in micromanagement. 6. Calls at an odd hour are the Norm. 7. To quote one of the directors " we are paying the vendor and we will try to squeeze as many services as possible". The company will pay you too, I don't have to say more.
