Waitrose interview questions

Do an online questionnaire and if succesful, do the situational judgement test. After i passd that i had to wait until i saw another screen which asked some basic questions. I was then called in for an interview. When i got there there was two other prospects there and we were then caled to go into a room with the store manager. we had to do a group excersise wherehad to pick the most appropriate items for a shopper and also another one where we had to deal with a mystery customer. After that we had to wait for another deputy manager who walked us around the store whilst conversating with us and asking stuff like your favourite super hero etc it was quite informal. We were then told to go and to wait for a call back. I got the call the next day (saturday) and was offered a contract and asked my uniform sizes etc. This interview wasnt like the other ones i had at waitrose (been to two before) as in the others wernt as straight forward. This process literally too 5 days werever other interviews have been dragged out to nearly a month so i guess it depends on the waitrose you apply for.
