Harrods Assistant Manager interview questions

Had a telephone interview that took around 30 minutes. Competency Based Questions that became repetitive after a while. Furthermore, got called in for a 1:1 attended. The same questions were asked which was a bit overwhelming. Maybe they needed to see your body language and your appearance which is totally understandable. Furthermore, I received a phone call a week later stating "you are driven, passionate, all things that we are looking for. Love your background and how you are. However, you are unsuccessful at this time because 'you talk really fast.' Nonetheless, having a Bachelors and a Masters Degree in Communication should be a plus when it comes on to communication effectively and having the positive tone when speaking to clients and team members. I was also told " Incase a stakeholder walks in they need to understand what you are saying." First of all, I speak English very well. Secondly, who would of thought your education and what you are a master at would be a downfall to working for Harrods. Anyways, if that is feedback that you give to your candidates, you might want to come up with another way to effectively communicate with potential candidates.
