Strong favouritism, inconsiderate higher management. It looks fun from the outside, passionate people doing important projects. It is a scam well planned, you get no appreciation for working on weekends and extra hours, no benefits, no overtime pay. In hard times, plan B is to cut cost at the expense of the employees and their mental health. The remaining employees gets squeezed and burnt to their limit juggling between projects. This is a hire fire bully company. Be careful with what they say to you, mostly fake, manipulation.
