Is it your first time to undergo a job interview for the past five years? Or is this probably your first time to undergo one?
I know that you have the tendency to be worried and nervous before the interview because you don’t have any idea on what questions will the interviewer ask. I advise you to ask a friend who is in a managerial position to do a Mock Interview with you. Most likely, your friend has an idea on the typical or usual questions being asked. Answer the questions truthfully and this can be a big help. Don’t play around and be serious about it. Remember, practice makes perfect.
