I applied online. The process took 1 day. I interviewed at Oblix Restaurant at the Shard (London, England) in Feb 2016
Interview
The interview was good and quick. I think that they already decided that they liked me. I wasn't asked any of the normal interview questions, instead was just told about the business, and was invited for a trial day the next week. After my trial I was congratulated and got the job! The whole thing took a week.
