Pros
You become mentally tough and learn to take the verbal disrespect of your superiors. Other companies know what kind of a reputation IDR has and know that despite the reason you left, you are a hard worker and were just in a horrific environment.
Kontras
The CEO is an absolute nightmare with a horrible temper. He will get up in your face and scream at you like you are a piece of trash. You are mistreated constantly and don't get a break at all during the day. You work 12 hour days and are expected to clock-out after 8 and work the rest without pay. If you have an issue and need to discuss it with your superior, the response is implying that you don't have mental toughness, you aren't driven to succeed, or some other demeaning comment. If you are thinking of working for this company and see that current employees have written GREAT reviews, that is because your boss will force you to write something positive about the company. There was 100% turnover with recruiters while I worked there. You are promised the world and treated like you are more than disposable. My advice is to think twice before working here.
