Deichmann interview questions

Had an interview for the role and got there 5-10 minutes early as I always do to be told someone had called in sick so we couldn’t do my interview until someone else arrived in around 10 minutes. Asked them if they wanted me to come back and they declined. 15 minutes passed and told it would be another 5 so already off to a bad and unprofessional start. This is something I personally feel they should have called me about earlier to push the interview to later in the day. The manager had asked me to bring a copy of my CV as their laptop was broken, brought this with me and it was not needed. Was made to do a very old-fashioned and unnecessary maths and English test which the manager sat and watched me do - very off putting! The interview ended and I never heard back, despite being overqualified for the job. Very rude to not even inform applicants they’ve been unsuccessful. Manager was extremely unprofessional.
