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. There were 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 was more of a chat really, where they asked some generic questions and then asked about salary expectations, notice period etc. I received my offer the next day.

Every single person I have met during the process has been really friendly and approachable.

Why do you want to work at Mastercard?

Tell me three things you can bring to the team.

Tell me about your current job/responsibilities.

How would you investigate an issue that happened on a production server but you can't replicate it locally (i.e., server crash)?
