Same as others have mentioned - beware of this company. They try and reel you in about growth and going public, but it's actually through a shell company which is a sketchy route private companies take when they lack quality and just hyperfocus on profit.
They appear to enjoy wasting your time. I first got an email rejection immediately upon applying, but then they reached out to setup an interview. I was told the technical interview would be hard but it was actually really easy. I created a full functioning tool for traders to show that I know how to work with the full stack since just creating an API seemed too simplistic after being told that their technical interview was going to be difficult. During the interview, they mentioned that they were looking for solely an API which I was confused by since it wouldn't assess any front-end skills whatsoever, but I made the change anyway in front of them and showed it was working. They then rejected me because I didn't make the API from the start.
Worst of all, they made it seem like I didn't understand what an API was, and the cherry on top was that during the interview the developer had the nerve to explain to me what a Pull Request was (I've had a 15-year career in software development). That showed me that they had a clear prejudice towards me going into the interview, and it was quite insulting to be treated this way. The level of arrogance is a huge red flag about what the environment would be if you worked here - think twice before applying.
