I worked at J Sainsbury full-time (More than a year)
Good pay, great bonus, nice work culture.
Hardly any. Kinda faraway from transport links. But that is me, not driving.
Advice to Management
We need more free food!
I applied through a staffing agency. The process took 1 day. I interviewed at J Sainsbury (London, England (UK)) in May-2015.
I went through to the job via a recruiter, and after a week or so was called into a face to face interview where I talked to two managers (hring manager and one other) and had to do a very simple SAS test, which was explaining some written code.
Recruiter got back to me with an offer 3-4 days later.
The process for contractor hires is very simple and straight forward.
