Unbounce UI Developer interview questions

To apply you must build a landing page, which I actually really liked. It was a chance to dive into their product. Had a casual interview over coffee, which resulted in a formal interview with the team I would become a part of, and finally a phone follow-up for references and salary negotiation. It was friendly and casual. I was asked to walk through my portfolio, thinking processes, challenges, etc. My only critique is that I felt strung along for a while. The interview process lasted around 4 months. I later found out it was because of timing with budgets.
