Group interview, where you're split into groups and cycle through different tasks manned by different staff members. Some may include doing hand/arm massages, roleplaying a demo of products and explaining it to customers, or showing proof of active listening. If successful, onwards to a trial shift where you'll have an hour to work on the shop floor and showcase your ability approaching customers - basically a tester of how you'd likely perform if hired (so give it your best, if you're too quiet or nervous and not proactive you won't get the job).
Not the most neurodivergent friendly process however.
