I believe it was a few hours long. A group interview where you would display whether you can serve tables and pour whine correctly. It's more of an explanation rather than an assessment as those that didn't do a very good job were hired anyways.

It was a group interview there was 18 of us , I had to bring my passport and references. We then had to introduce our selfs and they then showed us a presentation. Afterwards we were shown how to open and serve wine, how to lay out the table and how to give the guests food and how to clean up and carry 5 plates. We were assessed on our performance of these task. Then we did a health and safety test which consisted of multiple choice and open questions we had to get 15/20 pass. It took 3 hours and we were given a five minute break where they provide us snacks

Submitted my application for the open day. There were A LOT of people. Waited in line for about an 1 hour. Once I got in, I sat down in the line and filled in the form, got my picture taken and was taken as a group to the first room where we met the owner of the company. Then second room was a practical exercise: setting table, opening wine bottles etc. Then last part was meeting with the bookers where they took your CV and asked general questions. Heard back within a week with a job offer.
