OP has posted this link before, both here <a href="https://news.ycombinator.com/item?id=10990206" rel="nofollow">https://news.ycombinator.com/item?id=10990206</a> (with the title "Get an interview at LinkedIn by solving this puzzle") and on the Who's Hiring threads <a href="https://news.ycombinator.com/item?id=11014173" rel="nofollow">https://news.ycombinator.com/item?id=11014173</a><p>As an exercise, I wrote a quick and dirty python script to solve this back in February (albeit it's not the most elegant solution but far better than brute force) and submitted my answer and subsequent contact info hoping to eventually hear back about said interview, and never did.<p>Which is quite frustrating from the perspective of someone on the job hunt. Why use something like this as a hiring tool and not follow up on it?<p></rant>
If you enjoyed that, there's plenty more where that came from at <a href="https://regexcrossword.com/" rel="nofollow">https://regexcrossword.com/</a>
LinkedIn thought, "We have a problem, not enough good devs." Then they thought, "Hey, let's recruit using a regex puzzle!" Now they have two problems. (With apologies to jwz.)
This is typical of the same crap I see on my linkedIn feed.
Solve this if you are a "GENIUS"!!!!
popsicle + popsicle = 6
toilet * toilet = 9
popsicle + toilet =???!?!??<p>I have made heavy use of the block feature. And to those of you thinking of answering those, its a lose-lose proposition, you either get it wrong and look ignorant, or you get it right and look like a slacker...
Solved this puzzle last time and LinkedIn basically told me "we won't actually interview you unless you have 2-4 years of industry experience" new grads be warned.
I solved it! They reached out about a day later (edit: and asked for a copy of my resume) and showed me a couple of job listings I'd be a good fit for. They wanted me to relocate which was kind of a buzzkill, but it was fun getting to talk with one of their engineers about how they've set up most of their projects. They were super nice, but it does take a while to hear back from them.
It was fun but pointless. I would have been more impressed if the solutions were unique and dictionary words rather than trying to make silly regexs like 'not working'. Is LinkedIn even hiring with their current stock plummet and rumors of layoffs?
