1. Important qualities.
I believe that all these qualities are important in an interview, which of them stand out more depend on oneself. I mean, when you're so pretty, it stands out, whereas when you're a normal person but your grades are amazing, this is what stands out.
The first impression is very important, but not decisive. Finally, it is the set of information that determines whether you are suitable for employment or not.
Also the type of work can determine which qualities are more important. It's not the same to be a fashion store saleswoman as systems analysts.
2. Job interviews.
I never had a job interview. Currently, I am still studying. In a short time I will go out to work in the world and sincerely I am scared.
3. Job advice.
Do not dodge your eyes, but do not stare at it like a psychopath.
