Conversica interview questions

This company needs to take a lesson in etiquette. A few months back I applied and received an email for a phone screen request. I replied and heard nothing. I reached back out and heard nothing. A couple months later I reapplied because the product still interested me. I received another request to which I did receive a response. The call went really well and I had a call with a team lead who told me I would hear back from the recruiter on all the next steps. It has been a few weeks, a few reach outs later and NOTHING. Although I get at this point they are not interested, it strikes me as extremely unprofessional to not send even a templated email declining to go further in the process. How hard can it be to type a persons name and press send? Unbelievable. Very cool product, terrible hiring practices in my opinion.

Multiple round interviews alternating from a phone call, to in the office and back again. When returning to the office less than a week later I was treated like a total stranger but otherwise, all interactions were extremely professional and positive. Currently, I am being 'ghosted' after 5 interviews, over a month of back and forth and multiple follow-up emails.
