Very small company, as it is a startup. This means that you see the same people, make wonderful connections, and get the opportunity to work with everyone. My supervisor was also very hands-on and truly wanted me to learn a lot and take away a lot from this experience.
What I wish was different
I wish I got to connect with employees of this company that were abroad or remote; they played a large part in the whole company and getting to know them more would have been helpful.
Advice
Interning with a startup is very unique and valuable. You can become very close with your co-workers and peers and obtain great experience that is useful even at larger companies and future experiences.
