Why GitHub Won't Help with Hiring

> If an employer can't ascertain your skill level through the interview process, their hiring is broken.

I think the better way of putting that is "Interviewing is broken". Determining that a candidate meets a minimum level of skill-set is possible to do in an interview, however, determining much beyond that is highly elusive. I've had candidates that were incredible "Used Car Salesmen", who the previous interviewers wanted to "skip the technical interview" and just hire the guy outright because he was so convincing only to have his outcome in the technical interview end up being terrible (and I've had candidates get the job where this fact was discovered too late)[0]. I've had candidates that I've had to have a fight nearly come to blows to get a candidate hired because they were so nervous that they completely bombed the interview, and that "accurate portfolio of their skill set" was the only thing, outside of my insistence, that got them hired (out of the few this has happened with, all were good hires, too).

I'm not asking anyone to jump through my hoops (especially now that I'm working at a place where I, thankfully, no longer interview candidates). I don't ask candidates to white-board code (I wouldn't let them if they wanted to), but given a candidate who has a solid portfolio against a candidate who does not -- assuming all other things are equal (or the portfolio is incredible) -- I'm going to hire the one with a portfolio. And I feel it is a personal responsibility of mine to keep that stuff up-to-date. I could do a better job of it, myself, but if I failed to get a job because I lacked in that area, I wouldn't blame anyone but myself.

[0] I blame myself for this one -- he could talk up and down about concepts; was hugely into functional programming at a time when that was less mainstream. He not only knew all of the buzzwords, but he knew the "why"'s behind them. Academically speaking, he was incredibly knowledgeable. It wasn't until he had to actually learn an existing code base and contribute to it that it was discovered he lacked in execution. A manager on his team felt that he "froze up" ... would write something seven different ways and keep coming back to it while writing follow-on features until all he was doing was modifying code he'd already written to yield the same result, just slightly differently. I, arrogantly, assumed he was too good for the half-rate programmers we hired but upon running into someone who worked with him at the company he came from, it was discovered that he was not actually employed by them at the time he was interviewing as he'd been let go a couple of weeks prior ... and he had the same problem there.

FYI: WordPress.com requires plugins to be GPL for their public marketplace, so there may be nothing "flagrant" going on at all.

I do the same as well, I think it is a great approach. It is just a paring exercise, the language of their choice, their equipment, full internet access. We just build something like a calculator or pig latin translator. Something that you build up in layers. I usually read off the test cases one step at a time, in hopes that they write their own tests along the way.

But hiring good people is very time consuming. The reason GitHub as a portfolio makes sense, is that it helps compare potential candidates--that I know nothing about--faster. Biased or not, I have had the best experience with people that are very active publicly. From Battlebots competitors, book authors, to startup founders, etc.

Ivy League Colleges, VCs, even Y-Combinator works very much the same way--trying to make an assessment based on past accomplishments. The more visible, the better. With the caveat being a strong direct reference.

I am sure we all have extra circular activities besides coding, but depending on how strong your experience or professional network is, really depends on how much you need in a portfolio. I have been coding since I was nine and have decades of experience, I still have stuff I hack on that is public, from SlackBots that control GPIO pins to Sonos controllers, etc. I would think the more experience you have, the better chances you would have more stuff you can add to your GitHub (portfolio).

At the end of the day, as a someone hiring, I am going to gravitate to engineers that have more and better examples of their work ability and output vs where they worked on their Resume. Not to say that we should ignore anyone that doesn't have public projects--but they are certainly at a disadvantage against someone that has.

And here you are on HN. It is hard to buy this argument. Instead of reading HN for a week, hack out a little app and toss it up on GitHub. I am almost certain that is more valuable for you than opining here.

I think that "having github will help you" is the same kind of advice as "prefer to provide resume in pdf over doc".

There are people who believe in it, it seems reasonable, but in reality nobody cares. Just another cargo cult.
