Olly Olly interview questions

Sent in my application - later I was sent an email with my name in all caps (obviously autofilled), and said they were moving me to the next round, and I just had to complete a questionnaire. I open the questionnaire, and it's all questions that should've been on the initial application. I answer them, obviously meeting the JD requirements - and a week later on a Sunday, I am sent a rejection letter with my name autofilled in caps not just once but TWICE. Obviously, this company lacks professionalism and if that's how they treat their applicants, I can't imagine how employees or clients are treated.
