My resume and when I interview I accurately describe my skills. Its been a while and I understand you have to "sell yourself" but I don't lie.
I do also try a hell of a lot harder than most and self-learn all of the time on my own time. So, there is that.
I brought show n tell stuff last time I interviewed for a job. It got me that job.
I've worked with some people who kind of exaggerated skill, however.
That is a great way to get hired. Having some "look, I did a thing" even if its stupid and simple and hosted on someplace like git-hub or your own website. (If you are in tech).
If I am interviewing you and you can show me something you actually did on the spot or describe something you cant really post publicly because its "company work" to a very high degree I know you know what you are doing.
If it would not possibly be a doxing issue I think I would start a sub on here for "practice interviews". Post the job you are interviewing for and a volunteer poal'er would run a mock interview. Maybe that is worth doing anyway. Still thinking over the "learn stuff" sub I posted about a while back (I think its been about 2 months at this point).
I brought some boards I designed and populated. People like stuff they can touch and ask questions about.
Jobs can be generic enough - post a link to something on one of the job boards - that you can apply that to other similar things. I think if you did it right there would be no fear of doxxing.
