I'm a teacher since 1998.
I think that in an interview all the qualities are important to make a good impression. Appearance is important because, after all, it is the first thing that interviewers see; also the qualifications are important because give information about the interviewing person; experience is also important as it means that you don't start to do the work from scratch, you already have knowledge of it; and personality is, after all, the decisive idea to get the job or not.
