Spotlight-hogging during interviews can convey the message that you’re self-centered and are not considerate of the interviewer and the other people who may be with you during the interview.
Have you ever come across a celebrity you admire so much for the looks and talent, only to be disappointed after hearing a live interview on television? How about politicians and the way they answer questions thrown at them during ambush interviews? Does it not amaze you when high-profile executives answer queries about a crisis their company is going through yet they do it with so much class and ease?
Handling interviews is one of the skills a person can master, even if he/she is not a celebrity, a politician or an executive. Since we live in a democratic country, we are all entitled to share our opinions; we never know when our personal thoughts on a national issue might be needed, so it pays to know and be prepared.
