Matrix Alliance Market Research Marketing Assistant interview questions

They started off with a zoom call and was not told that it was a group meeting. I was then invited to the office to meet the managing director again was not told it would be a group meeting with 8 other people there. There job advert was hugely misleading as it was advertised as a marketing assistant however when the managing director was talking through the job role it was a sales job going door 2 door getting people to donate to charities I do not consider this as marketing and it should have been advertised as a sales role.
