An interviewer is someone who asks questions to get information from another person, usually for a specific reason or purpose.
When we talk about an interviewer, we often think of them as a professional - like a journalist, a TV host, or a recruiter. They're someone who sits down with a guest, candidate, or participant and starts asking them questions on camera, over the phone, or in person. The goal is usually to get some kind of information, answer, or reaction from the other person. This can be for a story, a job application, or just to make a decision about something.
