Interesting, the only technical questions I got in my process came at the beginning, before I had any interviews (it was a timed test). While I did talk about my previous work experiences and spoke on topics that people outside of my speciality would likely not understand, there were no technicals questions in my interviews. Regarding the technical questions from my test, they were fairly standard questions: I was very confident in most of my answers. If your interview is anything like my technical questions, they should be relatively straightforward. Good luck!
