I'm a software engineer that runs a technical recruiting company. I worked at Microsoft and Netflix for a decade. Email me at robert at facet dot net. I will interview you and tell you why you're not getting hired.
If I ever met you, I'd buy you a coffee. You jumped straight in to help the OP without offering any kind of upfront diagnosis based on the very little information available. The traits are patience and humility. They're valuable and not often found.
I agree that the GP's offer is admirable and far better than mere feedback. But this doesn't obviate the value of honest, constructive feedback. His concern is explicitly about the impression he makes on others, therefore our impressions are valid to share with him.
This is refreshing! no grammar analysis, no inferring about mental disorders, no bragging about high ground you are on, not calling creepy, no calling OP over in his head... to me it feels like people are having a field day at OP's expense. OP: I suck!.. 999 people: AHAHA YOU DO BECAUSE YOU SUCK.
I went ahead and signed myself up to your website. The application made me feel like I wasn't supposed to, considering I've never done any of the things it asked if I did, and am just a lowly CS student who doesn't even have a great GPA, and is about to graduate jobless... so I figured I'd take a shot. Very nice signup process. Smooth as butter.
Completely understand if you can't help me, but would love some feedback on my resume at least.
I just offered the same thing, but my opinion isn't worth nearly as much as yours. Thanks for offering something of real value, which I saw only after offering my own, much less valuable, mock-interview. :)
