I was contacted on Linkedin from a Mastercard recruiter, I sent my CV and was invited to take part in a technical challenge which I was given 2 hours to build a web application and submit the code. I was later contacted to say that they were happy with my solution and invited me for a face to face with 2 people from the team. They asked a set list of technical questions and did a small whiteboard task, overall they were very friendly and easy to talk through issues with. Some non technical questions about the processes / teams I've worked on, how I go about solving issues etc. I was then invited back for a HR interview which lasted less than half an hour and more of a chat really, asked some generic questions and then asked about salary expectations, notice period etc. Received my offer the next day. Every single person I have met during the process has been really friendly and approachable.
