The company is oligarchic in nature, run by a group of individuals.
There is seemingly an unwritten policy of not speaking up. Doing so may cast you in a bad light and negatively impact how you are treated by management. Any constructive criticism brought to management may be perceived as a personal attack. Depending on the feedback provided by the employee, the managing group may collectively determine that the employee is overstepping boundaries and reprimand you. While it isn't explicitly stated (they verbally encourage the opposite in fact), it is likely that the act of speaking up for oneself may be looked down upon. There seems to be a working belief that being employed by Local Foreigner is a great privilege. Any perceived pros to the position can come at a high personal cost. The working environment may be detrimental to certain individuals' mental health.
Furthermore, it can be difficult to achieve a healthy work/life balance at the company. You may be expected to bring your work home with you and be available during weeknights and weekends. While office hours are typically 9:30am to 6:30pm, the de facto office hours may feel closer to 9:00am to 7:00pm. If anything does arise after those hours or the weekend, there's a chance that responsibility will fall to you. Finally during your paid time off, you are expected to be keeping up with emails and client issues so it may feel like you actually worked the entire time instead of relaxing.
If you were to ever start a job here, it may feel like you are working non-stop until the day you quit.
