This is DEFINITELY one of the most frequently asked topics in the Human Resource (HR)  interview rounds. You should not be too confident in your answer to this question. On the other hand, dealing with errors seems unreliable. Honesty is always a good idea. Here are some benefits that can be discussed in the interview:

• I am a goal-oriented team player and eager to learn new things EVERY day.
• My communication skills are exceptional.
• My ability to handle pressure and stay calm during difficult times sets me apart.
• I have strong leadership qualities that will benefit me in the long run.

Now let's look at some of the flaws  worth mentioning in the interview:

• When I am new to a certain technology or SITUATION, I have a lot of doubts about myself.
• I am a self-critical person.
• I am afraid of standing on a stage and DELIVERING speeches(afraid to speak in PUBLIC)

Admitting your mistakes is essential, but it is also important to explain 
how you have worked to fix them. This will give the interviewer the impression that you are always looking for ways to improve yourself.
