I know someone who worked in the design team and she painted an extremely scary picture of the company.
I know her work hours were insanely long. Her weekends were working as well. Additionally, she told me that were many instances of abusive behaviour which included the CEO and senior managers shouting and breaking down other employees, especially targeting women, or bringing in insane policies from time to time which included 25% monthly salary as fine if anyone did not follow his orders.
There were also rumours of the CEO emotionally and sexually abusing senior people for years on the pretext of a relationship.
I hope the investors take the required action.
