Liberty Global Software Engineer interview questions

Interviewer during the intro chat didn't give me the time of the day to speak about my experience in depth. They ask basic hr questions, which can be done over the phone. For preparation, I've been reading and studying about the company, but turns out they are hiring for a "start up" at Believ instead of Liberty Global. The company mentioned in their job descriptions, all the way to the email that they used for this role are pointing to Liberty Global. So it is very misleading for candidates that are preparing for this role.
