Hilti Group IT Technology Project Manager interview questions

I applied online for the Project Manager position. I got a system generated E-Mail as response that they had received my application. The next morning I had another system generated E-Mail in my inbox with a rejection. Since I fulfill all the requirements of the job ad, their reaction is not only weird, but also not acceptable. There is no E-Mail address or phone number provided so that I could get in contact for feedback. Odd and unprofessional!
