Quick small talk with HR and senior dev about myself and my experience. Then some 1 hour pair programming with another dev, where I had to write or fix some code in shared online editor. I had instant feedback and could discuss solutions with the dev who was running pair programming so that's good. Few days after that session I have been approved to the next step which was an interview with the CEO, mostly general stuff about company and my experience. In the end I've received an email saying they won't hire me, but without any explanation as to why they won't hire me. Anyway most companies I've interviewed at didn't reply at all, so a "no" email is still more than silence.
