My first thought was the way you dressed may turn interviewers away from you. Then you explianed that you did dress very nicely and wore minimal makeup. For myself, I have never worn much more than a little powder and some gloss and actually wondered if that was what turned people off. But, then I read where the more makeup a person wears, the slimmer their chance for the position. On that front: what about your shoes. Are they sandals? Are they heels? I am quite sure that you wouldn't wear flip flops, but I was always told that sandals were not a good choice. Always closed heels and toes. Heels are good on women as long as they are not stilettos, but 2" to 2 1/2" pumps. Black, Navy Blue and Gray are the most acceptable colors to wear for interviews and to avoid large, bold and/or colorful prints unless the position were something in the area of design. (between my junior and senior year of high school, I once wore a bright pink pull over sweater with an elephant stiched on the front. Probably not my best choice.)

I am sure that your resume looks fine on the outside, but most, if not all, resumes can be modified to attract the particular position or company that you are applying it towards. There are a lot of CV tips on these boards and I am sure that someone has, and will give you, a link but I have no idea of one.

My initial thought as far as the interview where there were 100 candidates and they told you that they were trying to fill over 700 slots: these people may not have been on the up and up. The only agency that I know of who look to fill that many positions at one time is the military. I would be leary of anybody else. But that is just me and was probably not the case in your situation.

Because I don't know you, I obviously cannot say this is true, but my nephew (18) believes wholeheartedly that his mother, father, grandmother and I need hearing aids. He can say "pass the butter" and what the four of us hear is "pa th bur". Try a mock interview with a parent or a friend to determine if you really do speak as cleraly as it sounds to you. Or, better yet, in your next interview, bring along a tape recorder and tape your answers. Later (3-4 hours) play the tape back to determine if you are slurring or running your words together.

I am wondering if the fact that you are still in school is putting potential employees off. If you interviewed for something along the lines of a summer internship, then this wouldn't apply, but if you interviewed because you were thinking of working during the off school months for experience and money and then returning to school to finish your degree program, the employer may think that training you is not worth the effort and expenditure since you will be leaving in just a few short months.

Lastly, I was thinking that, you may contact some Human Resource Departments or hiring authorities for places like grocery stores, 'Wal-Mart, Wal-Greens, etc and ask them to critique your skills. It sounds weird, but if you approach them and explain your situation that you would like to be able to interview in the corporate world and would like their expertise and professional opinion, they may be so flattered that they jump at the opportunity. (Yeah, I know, it sounds weird, but any port in a storm, right?)
