I was contacted for a job in Dublin. It started with a quick phone call with the recruiter, who then sent me a link to an online HackerRank test.

The test had three questions that could be answered in a few different languages. I chose Python.

After completing the test, an interview in the Dublin office was arranged. It was a technical coding interview consisting of three whiteboard questions, which were then to be coded up in either C or Java (preferably C).

After completing the first interview, a second interview was organized. This was very similar to the first, except it consisted of one larger question.

The process concluded with the company checking all my references.
