I applied through an employee referral. The process took 2 weeks. I interviewed at Mastercard (Dublín, Dublín) in Jan 2014
Interview
After being referred internally I was contacted by email to arrange an interview. I had two interviews, the first was a teleconference interview in the MasterCard office with two managers and one engineer from the St Louis MasterCard office. This was straightforward. where they explained the position, inquired about my experience and asked about some college projects I had worked on. Since this was my first job out of college the questions were quite general. After this I met with a HR representative a week later, I then received an offer which I accepted. The process was quick and easy, I had no problems.
