Serve Cornwall interview questions

When applying for this role, I stated I did not have recent serving experience. You have to attend a ‘Skills Assessment’ with other individuals. You have to arrive in their stated clothing such as black smart shirt, not a blouse, black trousers and shoes. I did not have a black shirt, only smart blouses, so I went out and bought one. The skills assessment included setting out a table, opening a wine bottle and carrying drinks on a tray etc I was confident that I had completed all tasks well. I did not hear back from the staff member who ran the assessment and when I chased them up, I was told I was not suitable due to my lack of experience. If I was declined initially due to this (which I had made clear in my cover letter), it would have saved me driving there, paying for parking and paying for a smart shirt. Overall, this interview wasted my time and money.
