It was a very fast, focused, and enjoyable experience. Unlike a lot of other tech companies (e.g. an HR-focused company asks about designing an Uber-like application!), they focused on some problems which relate to their daily routines. Interviewers are really friendly, collaborative, and they are there to help you.
The entire team, including the nice CEO and CTO of the company value your time, are respectful, and very friendly. And you will be surprised how they process everything super fast.
