Firstly, someone from Guidewire HR contacted me for an initial call, after that they sent me a Codility Test, then I had an interview with one of the guys where he asked me about my experience and some questions about java, encapsulation, recursive, etc and finally a 3 hours interview on-site, three different people, all of them really kind and helpful, here I had to do some coding on a whiteboard.

It was overall a good experience. Interviewers was nice. Three rounds back to back. Some oop fundamentals questions then onto some sql queries. Not too difficult. More behavioral than technical I'd say.
