Vodafone Sales Associate interview questions

Basic online questionnaire, then video interview of sending clips to answering questions and then face to face interviewinh to act as I was selling a phone to a made up company and make a presentation in 10 mins for interviewer as if they were company and role played as a member of staff and angry customer, 10 mins to prepare again and then general interview questions, was quite a lot just to sell phones and i feel like the multiple interviews leading up to the face to face is so unnecessary. Have a lot of knowledge around technology etc but just make sure you have a good background in sales and customer service to complement this or youre honestly wasting your time. Overall seems like far too much for the role and I'm glad I didn't get it although interviewer and other staff were very pleasant.
