First interview was a nice conversation with some technical questions and discussing my current role and expertise that can be applied to this new role. The second interview I was asked to perform roughly 3-5 hours of work for free that can directly improve their current service / product. Unprofessional and disrespectful.

Quick and cordial, friendly and asked a lot of relevant questions. Very helpful in answering questions I had regarding the job, like exactly what I would be doing with who and where.
