This is probably bait but FYI it’s not normal to send thank you emails in much of the world following an interview so perhaps consider that not everyone thinks like you and it’s not a slight to receive no thank you emails. Where I live a thank you email would be seen as a strange way for someone to sneakily try to persuade you to hire them outside of the proper interview process. If you don’t get an email you may just be dealing with someone not from your culture.
