Pluspunten
The only advantages that I see are the employees and by employees I don't mean managers I mean the people that have to fight every day to survive in a company where there is absolutely no long term strategy and where your position can disappear after an investor round. It creates solidarity between people.
Minpunten
No (long term) strategy. They open international markets before having done any market analysis. Therefore, they can open a shop, hire an entire team and 6 month later fire the whole team. Like in any startup you would say? Even worse, the HR department who doesn't support employees in any ways will make you dispappear in 24h: the head of HR will call you for an interview usually early in the morning or late in the evenening, pressure you to sign an agreement (taking advantage of the fact that as a foreigner you don't know your rights), and ask you to leave immediately without chance to say goodbye to your colleagues.
Several teamleads are totally unskilled that leads to very high turnover in some departments. Despite complaints and turnover top management and HR let them act badly (no vision, inappropriate behaviors...).
Very low salaries
A lot of extra hours not paid obviously
