Pets at Home job trial

I had an interview last week for Pets at Home for a new store they are opening. I have just been offered a work trial for sometime next week (yet to be arranged).. Anyone with experience of working here, are you pretty much guaranteed the job once you have reached this stage? Don't want to get my hopes up too much about finally being able to quit my current employment (hopefully!) if it's still not too guaranteed!

Did you go through the group interview? Most of the time, from past Pets at home posts here (I`d suggest searching for them for tips on the work trial They are almost guaranteed the job but it depends on each store
