I loved the team. Perfect match with all passionate people. You experience the entire production process inside the company, from building the features to see how customers receive it.
What I wish was different
It being a startup, and considering the fast environment, the supervision was not enough. You are sometimes left to learn by yourself. I wish there was more people to guide.
Advice
Definitely get ready to work hard. The amount of experience you will get is priceless. Everyone will encourage you to learn new things, but the fast environment may overwhelm you time to time.
