As a suggestion, point people to a personal web page or portfolio. Especially for a front-end engineer, I would never recruit someone based on a LinkedIn profile. That's doubly-true in this market. To make it through the filter, it doesn't need to be fancy or take a lot of time, but it does need to be tasteful. Of course, fancy and playful go a very, very long ways for separating yourself from all the other people wh…
Plenty of other people will recruit him. The guy has worked as a front-end engineer at Uber and Tesla. Just fill out the LinkedIn profile - bullet points under the Uber section. Link to GitHub if he has it, then post something on LinkedIn. How many people have personal portfolio sites that are 2-3 years out of date... even 4-5 discussing how to build a product list in Backbone.js.
And to your comment, most portfolio sites are years out-of-date. I don't know anyone particularly cares. Most also aren't called 'portfolio sites' but 'personal web pages.'
If someone wrote a good backbone.js web site a half-decade ago, that gives me a pretty good indication of, well, a lot of things I care in hiring. I'm not making a check-list of technologies people know. Most experienced engineers can pick up new technologies in a month or two. I'm more looking for the sorts of things which are timeless:
* For a UI/UX designer, is there a sense of style? Did they think through what I want from their web site and how I get there? If that's a not the latest styles, that's okay. I respect the people who designed NextSTEP or Amiga too.
* For a front-end engineer, is the HTML correct? Accessible? Semantic? Is it split up properly between JS/CSS/HTML? All of this will be second-nature to someone I'd hire, but I see a lot of people are missing basics somewhere or other.
... and so on.
Basic skills gaps, (1) I haven't seen new hires close (2) are often indicative of deeper problems. That's why those stereotypical algorithmic interviews came around for back-end. People now optimize so much to the metric that it's become a lousy metric (and why I don't trust interviews much anymore), but the basic concept is right. Smart people who understand fundamentals, learning quickly, and execute well / get stuff done, preferably with good soft skills.
I'll also mention: I'm not sure anyone's getting hired overnight right now. We've gone from a seller's market to a buyer's market. A lot of layoffs, and not a lot of hiring going on right now. In previous downturns, which were much milder than this one, I saw very good people on job markets for months, and average people sometimes for years.
