Standard assessment center, one group activity, one personal task and one short one on one interview. Nothing technical asked during the process. Was a pretty relaxed day. If you are confident in speaking and have done some light research on the company you'd do fine.

Interview
Online interview felt informal and interviewer was friendly and encouraging. Mostly questions on soft skills, not many technical ones.
Assessment centre had a presentation on your own development journey and a few activities in groups and individually which involved mostly considering different environmental, social and operational aspects of nuclear power and presenting conclusions to assessors.
Interview questions [1]
Question 1
How has your personal development prepared you for this job?
I applied online. I interviewed at Sellafield Ltd in Nov 2025
Interview
Very positive and relaxed interview. There was two interviewers, one being the head of dosimetry, and the interview lasted for around an hour. There were the generic questions like "when was one time you had to take the lead", and "how do you feel in an ever changing environment". Then there were some more targeted questions like "what does safety mean to you, and why is it important?". Some questions were about times in my life I've had to enforce safety rules, either for myself or others. They asked about what I felt about sellafield's core values and why I wanted a placement year. There wasn't much about technical knowledge.
