As far as job searching--i realize you made these videos in a casual everyday setting, hence the unkempt hair and casual clothing (which believe me, I do as well in casual circumstances). But I would hope you show up to interviews dressed professionally and with your hair a lot neater. I'm not really that much into makeup and i know this sounds superficial, but it really does make a difference in presenting yourself both to an interviewer as well as to romantic prospects. It projects confidence and contributes to the impression (sad, but true). The good news is that my statements are based on you being a clean canvas, so put a little makeup on there (a little lipstick, eyeliner, mascara, blush), fix up your hair, put on some earrings, get you in a suit, and voila!
Despite the casual nature of these vids though, and despite what you might wear, you seem very VERY nervous, so much so that you're even panting every so often, swallowing hard every so often
Your eyes are darting off to the side, like you're scared of something. And you're slouching a little bit with your arms close beside you. Open up your shoulders. Voila! Instant confidence! Smile full force! Be EXCITED to be interviewing for the job!
p.s. All of this advice is meant to impress for job interviews. And isn't necessarily directed at type related things (not all of it is). Based on what you said in the videos, I see you as a highly intellectual, smart, motivated person (and i'm not just saying that--this is my primary Ne speaking the truth). So everything I said is meant for presenting that mind and spirit of yours on a more congruent platter for job searching purposes. People unfortunately judge books by their covers more often than not.
