There is an initial face-to-face interview at the venue and if selected, you are progressed onto a trial shift.
Avoid this place like the plague, the trial shift is 4 hours and extremely busy, I worked on a bar with just one other person, with no managers or supervisors and was not offered the job. Essentially allowing the organisation to gain help with no return. I have a wealth of bar experience, so there was no reason that I would not be offered the job.
