Applied online, heard back within a few days and was invited to a recruitment day. First part of the recruitment day involved a mental maths test that involved around 20 questions, mostly money related, some just basic mental maths. After that had a short interview. Heard back within the next two days inviting me to a trial shift the next week. After the trial shift I was called back the next day offering me the job

HR Phone interview. Generally quite easy and conversational. General questions about who you are and work experience etc. Pretty much a box ticking exercise, do you have right to work and over 18 etc.
