A very good thought out interview. I completed the form on their site and after a week or so I was contacted to make video of myself answering 4 questions.

The process is quite non-standard and fun. It's really cool because one gets a chance to collaborate with the hotjarians, so she can see how the communication in the company works. Another thing is: most of the companies require you to do some coding exercises, but that's the first time I had to do a demo of the code I've written. The downside is the length of the process - it can take even 2 months to finish all the stages.
