When asked to talk about yourself in an interview, you want to avoid sounding narcissistic. You can avoid sounding narcissistic by being humble and asking the interviewer what they want to know about you. By getting an idea of what the interviewer wants to know, you can pick your words carefully and share the needed information, not excess information that will not help you get the interview. By showing that you are okay with talking about yourself without boosting too much, you are more believable and have a higher chance of getting the job.
