On All Fours Cat Sitting interview questions

Found the job posting for this online, Applied through a long application with a million questions. Filled out as much detail as I could in every single one and never got so much as an acknowledgement for the application back being sent. I think its very rude but after I submitted the application I looked spent some time doing research on this company to find out that it has some shady reviews and pretty bad situations from customers. I also feel like the least the owner could do is respond to applicants with a thank you for applying note since I can't imagine a million people are applying to her company all at once that's its too overwhelming to take the time do so - especially when you are requiring people to spend a lot of time filling out your online application form. It also seems like this business is being operated out of someones apartment, so no real office location.
