The interview process was very long. I first received an email in April to interview and 4 months later still wasn't made a solid offer. The process begins by speaking with a linear accelerator manager. He was extremely kind and the interview took around an hour and a half. He asked mostly about my resume. The next round of interviews were with a panel. This was pretty difficult, you have to prepare a presentation that highlights your achievements and answer to scrutiny. Finally, you meet the team and see how you fit in.
