Interview process
The interview for all STP trainee positions take place in Birmingham. They include 4 interviews/assessments, in a 'speed-dating' type setting.
You have 10 minutes at each station, where you are interviewed by 2 people at each. 2 are based on your specialism (Medical Physics in my case), one was general Science and Maths, and the fourth was more questions you'd typically get for any job interview, about your aspirations and motivation to apply for the job as well as a chance to get your personality across.
Most difficult question
Some in depth medical physics questions, which without my MSc in Medical Physics would have been very hard (it is not required that you have medical physics experience, only Physics and Maths).
Before the assessment/interview day, numerical, logical and verbal reasoning tests were carried out online, these were very difficult.
Interview tips
Read around the subject you are to specialise in, as well as general scientific knowledge.
Read journal articles / magazines such as New Scientist.
Join up to IPEM / other relevant professional body if offered before/after the interview takes place.
Experiences at the assessment centre
It was very well organised, with each interviewee being given a starting table, and a way to move around to the other 3. Also a bell is rung to identify when each 10 minute interview should be finished. The trainee is then given a 2 minute break while the interviewers make notes.
