I applied and a few days later I had my first interview. This was an initial screening to make sure that Uncountable and I were a fit in terms of values, expectations, and goals.
I had my second interview two weeks later and this was a technical interview. It had three questions in total.
My final interview was a few days later and I got to meet another team member for a chat. They demoed their product and was asked to show something I had built. Unfortunately I had some bug in my program and didn't get it to run. The interview was successful despite this.
