There were two stages. The first was a Skype call with a developer from the Dublin office. It consisted of technical discussions about testing, design, and one coding question with a walkthrough of the code once it was written. There were some internet issues, and the call had to be rescheduled. The developer was very nice about this.

The second stage was a half-day interview panel, with one developer/manager for a round of 35-40 minutes each. There were five people doing this at the same time as me, so we just switched interviews for the next round. There were 4-5 rounds of this. This started at 8:30 am in their Dublin office so they could have time to go through everyone.

Interviews arrived late. I had to write my name down for the receptionist to print a name tag for me. They got my first name right, but my last name was just a jumble of letters. I have a pretty normal Irish name, so they must not have been able to read my writing.

Each of the interviews started with talking about past internships I had, the role I had in them, and the development I did as part of them. The questions asked were normal for the most part.

There were some standout moments, though:

• I asked an interviewer what they liked/enjoyed about their time at work at Microsoft. They replied that it was different for everyone and proceeded to skip the question.
• One of the interviewers forgot my name (my name tag was on). The same interviewer had to go to the toilet as soon as the round began, which lost interview time. They started a question off with, "If you were a game developer..." (I wasn't, and the job had nothing to do with games).
• The HR person for the day, who apparently did seven rounds of interviews to get their job, had no idea that I was still attending college and had to go there after the interview.
• The second interviewer was the only one to mention the messed-up name tag.
• I got a "free" hoodie out of a mess of a day. I missed a two-hour lecture for nothing, really, that day.
