Are you sure this is a legit job? Because it sounds like one of those craigslist scams. But, to answer the question, mention whatever you think your best qualities are - dliligence, punctuality...whatever.

Interviewers want specific examples, not someone blowing smoke....... so you recall an example of what you 'did, when, how' and exactly how it reflects closely with the job specifics you are being asked to do in that particular job, so they can compare what you DID...... blowing smoke is..... "I would do this...." or "I am good at that.." or " I believe........"

tell them you have the experience and qualifications for the job

i would say "because i am perfect in everything"

Because I believe I have the necessary qualities to not only fulfill the required duties, but I can excel in this position.

I will take pride in supporting a team.
