I have passed pre-screening coding challenge, passed several interviews, including the one with CEO. After that had the official offer, and accepted it. After that I had a Skype meeting with the team. After that I was invited to visit the team in office and said "We will make final hiring decision after your visit" (???). I suggested the manager to give me a test assignment if they have some doubts on my skills. But they did not reply anything to that. I asked the manager of what shall I learn before the visit, and learned that. Obtained visa, visited them, spend a half of day in their office learning the docs and fixing bugs in their samples. After that I was said "We revoke your offer". Because you "do not fit the team well enough", and "not enough enthusiastic". It looks like something is terribly wrong with their hiring process. To be honest, I would not recommend to deal with that company in any way at all. And, if you've decided to apply, be prepared to jump up to the ceiling showing how you're excited by them and swear on blood that it was a blue dream of all your life to work with them. May be that helps. p.s. I can prove each and every word in this review.

There was several steps for this process, started with an online code test, then some more when I met a manager from Vaadin. The last step is to meet different team members
