Diamond Light Source Software Engineer interview questions

Short presentation, easy technical questions, one day on site, all was reasonably smooth and easy. Group task at the end. Adding some words to fill min. Recieved offer a week or so later.

I first had an HR phone interview. Then some months later, was asked to come to Diamond for an on-site interview which consisted of a technical presentation (15min) of my previous work and then about 30-40min of questions related to the presentation and my skills.
