so I have a interview tomorrow for a receptionist job at a local car company here in colorado I would be answering phones and doing data entry, I have one year experience as a receptionist and can handdle multipule phone lines. that was one of the requirments the problem is I get nervous easily and say the wrong things at the wrong time espically when there is compotition. and I know there is compotion cause he called me back yesterday and stated that he had been in interviews all day since saturday I asked him how stiff is the compotition and he said well as you know I have been in interviews but you do have a great voice, and that is what he is looking for so my question is how can I increase my chances for getting the job its like a dream job and how can i get over my nervous ness, sorry for being so long thanks everyone
