By being upbeat and having a positive attitude, you'll show the interviewer within the first few seconds that you are a "can-do" person who will be an asset to their organization.
2.) Being likeable
It seems basic, but it's a fact; people want to work with (and hire) people they like.
3. Being determined
You have to make it clear that you want this job more than anything else.
4. Being informed
You need to know about the company and what they'll expect you to do for them.
You need to quickly qualify yourself as a potential candidate; employers won’t want to take the time to do it for you.
