It took approximately 15 minutes and was held in quite a casual atmosphere. I felt like having a chat with the interviewer. However, the interviewer saw the candidates very deliberately.
I applied through an employee referral. The process took 2 weeks. I interviewed at Underbelly (Edinburgh, Scotland) in Oct 2019
Interview
Applied through the company website, then called to have an interview. The interview was also online over skype. It was relaxed and did not last very long. I did not have to wait long to have a response from them.
