Hilton Software Software Engineer (Ios Developer) interview questions

I think it was one of the weirdest technical interviews I ever had, and the first negative experience I have written about. From the start they were late and then the manager was uninterested and laughing throughout the whole interview. But the worst part was the questions that they asked, the manager was fixated on asking me weird data structure questions as if I am a backend engineer, and asked me things about how to store data in a database etc, I was so confused that I had to check again what position I am applying for. I understand I am fullstack but I would've expected iOS specific questions. And when I answered things in Swift he was confused and just continued laughing. I definitely didn't want to work there.
