Is LinkedIn a desired place to work? I've never heard anyone clamoring to work there.

Are you in the Bay Area? In my circles they are known as a good place to work.
That said, I don't understand why they've hired so aggressively nor what all those employees do, but they have a nice campus, good pay, and good perks.
What I got out of this: regex precedence rules are really unintuitive to me.
What is a precedence rule in regex? You can either derive a string or you can't. Precedence problems result in ambiguity, there shouldn't be any ambiguity here
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 =???!?!?? 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...

I work at LinkedIn. Let me be the first one to tell you that it is an amazing place to work at! Everyone is super smart and talented. The infra teams have some really amazing projects under their belt - a lot of which are open sourced. I work on the applications team and I love the culture in our org - everyone is super friendly, helpful and it's a privilege to be working on products that are used by hundreds of millions of people and being able to call shots on them. Also as a relatively inexperienced dev, I'm given ample responsibilities to drive my projects and mould them that I feel are helping me grow. The perks are absolutely amazing - pretty comparable to the ones you get at FB/Google. My favorite ones are $2k reimbursement for fitness related expenses per year, an entire week off during Independence day and Christmas, a day off to yourself and your team each month (search for InDays), and frequent company and team outings (there was a screening for the last Star Wars movie and is another one for Batman vs Superman soon). I'll probably never work for another big company again after this for an entirely different set of reasons, but I am absolutely glad about my decision to join LinkedIn.
Only 12% of people who attempt this puzzle solve it. Static text or real statistics?
I received the same stat.
Same here. It's probably a hard coded message. You'd think the hacker news post would skew it a bit if it was realtime. Either that or they have a really massive data set on it that's hard to skew.
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?

The regex operators can be ordered by precedence. The whole point is of course to avoid ambiguity...?
