The process was as follows:

A Skype interview where I had to talk about my previous experience, and a coding challenge that wasn't too difficult, as it's just the first selection stage.

After that, I had 5 interviews:

• A coding challenge.
• An interactive coding challenge with the interviewer.
• A design challenge.
• A discussion where I had to explain a previous project.
• A discussion with a non-technical interviewer, during which I was asked about my experience and my way of interacting with people around me.
