Pros
There are many interesting projects to work on. Many of my colleagues are super knowledgeable in the field and I've learned a lot from them in a short time. My manager has been supportive and makes sure that I can develop professionally in the direction I want to. The company vision is ambitious, and I feel that I'm part of something cool.
Cons
Some things are not as clear yet compared to established big companies, such as organisational structure, salary calculation, career progression, team goals etc. But there are efforts in the company to improve these aspects so I'm optimistic about the future. One thing I don't like is my laptop. It's a bulky and heavy Windows laptop without GPU. The IT department is rolling out new laptop and OS options, so hopefully it will be resolved soon. Although I must say I'm surprised at how slow it is for a startup.
