That very well could have been the reason why you were rejected for the other four as well, usually you never know when that's the case. Really hard to give advice on what to so differently. I will say this, not that any of this necessarily applies to you. Now more than ever, employers can find a tremendous amount of information about you before you even walk in the door. Your social media, court records search, etc. Then, it's how you present yourself. Very common for guys these days to come in with earings, unkept facial hair, visible tats, etc. Does that make someone bad person? No. Do people make judgements on that, if only subliminal? Yes. Same goes for women with visible tats, piercings, "extreme hair sytles, etc. Depending on the company/job none of that may be an issue. But for most places, it is. Fair or unfair. All of that is actually just part of the problem I see, and hear all the times form others in hiring positions. The entitlement attitude of the 20-30 yr olds. As with anything, this is in general- of course there are many who don't fit this profile. But I see more and more applicants who don't dress/ present themselves professionaly, but even worse come in with that entitlement attitude. "I have done this/that, that so I should get this job." It's important than anyone interviewing focus on what you can do FOR the company. Obvious? Should be, but amazing how rare that is.
