Humility is defined as a modest or low view of one's own importance; humbleness. Humility is important in life. All of us have things to learn from others, and we all make mistakes. We all have faults, and we could do better at most things in our life.
Most of us would not like to work with someone that is full of too much bravado. It's a turn off, and it creates resentment. Humility can be an important way to integrate yourself into a team during your daily work.
However when you're looking for an interview, or in an interview, you need to suspend your humility. You are the only person that will promote yourself, talk about your accomplishments, and sell yourself as a great employee.
Be humble, as much as you can, but not in the interview and not on your blog, resume, or annual review.
