Process was very easy. I had one phone call and after came to the office, talked with couple of people from business department, product owner and lead developer. Discussions were full of interesting questions about my experience and what is important for me if I would be part of the company.

Be ready for the tough question during the Technical part interview, you should be able to answer if you have the strong experience on the given tech. In general, great product, good location but crowdy office, will move soon.
