Pros
The friendships you build lasts a lifetime. Thats about it.
Cons
Outside to investors looks great but inside, well... This is a 996 work culture and/or black company. This was largely my and few others experience. Overworked, under-appreciated, underpaid, no respect. 996 work culture: The 996 working hour system is a work schedule practiced by some companies. It derives its name from that employees work from 9:00 am to 9:00 pm, 6 days per week. By following the '996' work schedule, you are risking yourself getting sick and possibly into the ICU. Black company (Japanese term): A typical practice at a black company is to hire a large number of young employees and then force them to work large amounts of overtime without overtime pay. Conditions are poor, and workers are subject to verbal abuse and "power harassment" (bullying) by their superiors. In order to make the employees stay, superiors of black companies would often threaten young employees with disrepute if they chose to quit. Surveys every quarter get worse and worse and nothing is done except "we're listening to you and you should say something". Yet when you do say something, its suck it up and be a man/woman about it. We've lost so many top talent people because of this poor culture and shift those responsibilities to others who are designed to fail because they don't have the support.
