I applied through a staffing agency. The process took 3 days. I interviewed at Defra (Reading, England) in Sept 2018
Interview
Straightforward and job offered quickly. Two people interviewed, one was a difficult sort of person (he's left now) the other very pleasant. Lots of security to get through to the interview and use toilets, too.
Interview questions [1]
Question 1
What did you do before and how does that relate to this job?
General skills they wanted and to see if I matched.
