The most important thing is whether he will give you an interview. But this is the premise. Whether you will succeed or not depends on whether you have the same topic. Can you have a pleasant conversation with him?

Regarding these questions, I remember saying them in "The Weakness of Human Nature"! ~! ~

Be prepared when you meet for the first time. What preparation? It's about his hobbies, his concerns and his background! ~

Remember: don't talk about the information you want when you meet for the first time. Because it's too abrupt, even if you get it, it's the same as outside. You might as well use someone else's! ~! ~ So, before you get the information, you should make friends with the interviewer and gain his trust, so as to get unexpected results. But remember, people trust you, you can't betray them, or you will be at your own risk.

Who wants to get better information, only you can get to know the interviewer first and make him believe you. You can get the information you want slowly.
