I applied online. I interviewed at Amazon (Tilbury, England) in Apr 2020
Interview
Simple. No real requirement only that you spoke English so that you could understand what was being said. Was short and was asked about availability, if I had concerns about carrying 15kg of items and such things.
There is a phonecall call interview only after finishing online application. When applying online, there are MC questions which are not hard to do. If everything's fine, a notification will be given for making an appointment for interview.
I had give my personal details and explain my availability for the job, and the interviewer was really kind and helped me with the interview, so overall it was a good experience.
