Very positive and pleasant atmosphere during the entire interview process, interviewers were quite friendly and gave me constant e-mail updates about the process.
All interviews were done via Skype because I live outside UK.
I had online skill test before interviews started, then
First interview where I presented myself and my work experiences, they also gave more detailed info about the opened role.
Second interview was with 2 developers from the team I was supposed to join, few questions from their side about JavaScript, Angular, AWS (more like a friendly chat)
Third and final interview was with the company director, again same style as 2nd interview but different topics.
They offered me job few days after the third interview.
Only reason I declined was the fact that I wasn't ready to relocate at the moment.
