One of my hobbies is reading books, but I have not been familiar withever really reading magazines much.

"Not familiar" with something means that you don't know about the concept, so in this context I would just say you don't read magazines much.

I thought, the information contained in magazines arewas outdated tha, compared to what could be found on the internet andor on YouTube, so I regarded thatem as an old culture thing of the past, like newspapers.

"Thing of the past" is a colloquial way of saying something is outdated, and sounds better here.

He said that it is a good way to practice speaking when reading that the parts about interviewsis to read the interviews contained in the magazines out loud.

For gettingIn order to get good answers, a magazine reporter should makeneeds to ask good questions.

Also, they makes good questions based on an interviewer's answer for nextust ask good follow-up questions based on the responses the interviewee gives.

"Follow-up question" is the term for a question based on the last response of someone

It hit me that it seems like a fancy game with sentences.

Not sure what you're trying to say here, the interview is like a game? In that case I would say "It occurred to me that an interview is like a game"

Finally, I changed my mind about magazines, and I am looking forward to nextreading magazines more.
