I'm a Reebok Sales Engineer! (5, Funny)

garcia (6573) | about 10 years ago | (#10265928)

NPR is clueless. That's why I am the one getting hired by Reebok! The URL was really 1828675309.com and let you to an OGG of Blink182 singing the standard Reebok commercial. At the end you were asked to go down to Foot Locker and buy a specific pair of shoes. On the bottom of the shoe was a keypad. Once you dialed 1829675309 you were connected with a Reebok HR rep and giving a job at a local Foot Locker.

Job as a Google engineer, sheesh. What a load of crap! Would you like whitener or a pair of extra soft socks with your shoes? Perhaps a Nuggets jersey?

Presumably they are looking for geeks to apply. They put that out there and it gets posted to Slashdot (which they probably expected) and gets deciphered in less than 20 minutes or so (which they also probably expected) and inevitably results in lots of geeks pondering applying to Google.

Sounds reasonable and gets them good exposure at the same time. There is a reason why Google is a household name. This is one more example.

about 20 mins worth of programming, and i'm not that smart. it ends up taking you to this page.

This one is actually quite easy. We look for a particular host name in Google's address space. So let's try:

$ host www.google.com
www.google.com is an alias for www.google.akadns.net.
www.google.akadns.net has address 216.239.59.147
www.google.akadns.net has address 216.239.59.99
www.google.akadns.net has address 216.239.59.104
$ dnslog 216.239.59.0/24 | grep '^[1-9][0-9]*\.com.A'
$

Hmm, no luck. What about the /16?

$ dnslog 216.239.0.0/16 | grep '^[1-9][0-9]*\.com.A'
466453.com A 216.239.37.99
466453.com A 216.239.39.99
7427466391.com A 216.239.53.184
466453.com A 216.239.57.99

Why Linux? (0, Troll)

NessusRed (710227) | about 10 years ago | (#10265943)

Intellectual Theft As a consultant for several large companies, I'd always done my work on Windows. Recently however, a top online investment firm asked us to do some work using Linux. The concept of having access to source code was very appealing to us, as we'd be able to modify the kernel to meet our exacting standards which we're unable to do with Microsoft's products. Although we met several technical challenges along the way (specifically, Linux's lack of Token Ring support and the fact that we were unable to defrag its ext2 file system), all in all the process went smoothly. Everyone was very pleased with Linux, and we were considering using it for a great deal of future internal projects. So you can imagine our suprise when we were informed by a lawyer that we would be required to publish our source code for others to use. It was brought to our attention that Linux is copyrighted under something called the GPL, or the Gnu Protective License. Part of this license states that any changes to the kernel are to be made freely available. Unfortunately for us, this meant that the great deal of time and money we spent "touching up" Linux to work for this investment firm would now be available at no cost to our competitors. Furthermore, after reviewing this GPL our lawyers advised us that any products compiled with GPL'ed tools - such as gcc - would also have to its source code released. This was simply unacceptable. Although we had planned for no one outside of this company to ever use, let alone see the source code, we were now put in a difficult position. We could either give away our hard work, or come up with another solution. Although it was tough to do, there really was no option: We had to rewrite the code, from scratch, for Windows 2000. I think the biggest thing keeping Linux from being truly competitive with Microsoft is this GPL. Its draconian requirements virtually guarentee that no business will ever be able to use it. After my experience with Linux, I won't be recommending it to any of my associates. I may reconsider if Linux switches its license to something a little more fair, such as Microsoft's "Shared Source". Until then its attempts to socialize the software market will insure it remains only a bit player. Thank you for your time.

if it would be acceptable to hack a whois database to see what domains are registered to google.com and just go there without solving the math problem. In fact, maybe they'd prefer that way, since Google has nothing to do with prime numbers but everything to do with the Internet.

I presume that would work for billboards where 'Google' is prominently displayed somewhere on the billboard. From the images I have seen of the billboards, it ain't there.

Given a Billboard where the only content is a text string '{first 10 digit prime in e}.com' there are three ways to find out that it is a 'google' ad.

1. Solve the puzzle.
2. Bribe the billboard owner. (surely you have seen this billboard advertizing itsel out at one time or another.)
3. Wait till the news breaks that it is a Google Job offer.

Something tells me that Google is more interested in people who quickly solve #1, vs people who can handle #2, or wait for #3.

Monday, July 12, 2004 Warning: We Brake For Number Theory
If any Silicon Valley drivers have found that traffic is moving more slowly than usual these days on the southbound 101 right around Ralston, you may have us to blame. Last week we unveiled a billboard that's a bit unusual in that it promotes Google only to one very narrow constituency: engineers who are geeky enough to be annoyed at the very existence of a math problem they haven't solved, and smart enough to rectify the situation.

Google Billboard

In other words, the billboard (which offers problem-solvers the URL to, sorry, a page containing an even harder problem), is a recruiting campaign. We've always worked hard to hire the smartest engineers we can find, and we thought this would be a cool way to find a few more. Perhaps including you. If you're a math or computer whiz who doesn't happen to live within shouting distance of Palo Alto -- good luck, and we're looking forward to hearing from you.

In a kind of geek "Jeopardy," the billboard read:"{first 10-digit prime found in consecutive digits e}.com." The answer, 7427466391.com, would lead a puzzle-sleuth to a Web page with yet another equation to solve, with still no sign the game was hosted by Google.

Mastering that equation would lead someone to a page on Google Labs, the company's research and development department, which reads: "One thing we learned while building Google is that it's easier to find what you're looking for if it comes looking for you. What we're looking for are the best engineers in the world. And here you are.

Thats precisely what I did. Total time including googling for a million digits of e (massive overkill, its in the first couple hundred, iirc) and a list of primes, plus writing the perl script was about fifteen minutes.

The second question was even easier, but I'd seen a problem in that vein in an IQ test or something when I was a kid, and being a total moron when it comes to math, it was the first thing I tried.

20 minutes to solve both, just to get to teh damn google jobs page, a job I wouldn't want.

meganthom (259885) | about 10 years ago | (#10266028)

Personally, I like this approach. Maybe the problem isn't extraordinarily difficult to solve, but the ad itself has a useful purpose for Google's HR department: it finds people who are willing to solve a problem whose solution is not immediately obvious without any immediate gain, other than satisfying their curiosity. That has to be a nice plus for Google. They can limit their hiring process to those individuals and from there give them more challenging problems, take them through the interview process, etc.

I won't post the URL, but here's what it says in case you want a jump on the second question;


Congratulations. You've made it to level 2. Go to www.Linux.org and enter Bobsyouruncle as the login and the answer to this equation as the password.

Unfortunatley, the fun ends here. When you enter the correct password, you are taken to google lab's hiring page which I presume is accessible without jumping through hoops.

Outcry against google inminent? (1)

perseguidor (777194) | about 10 years ago | (#10266113)

Well, having received all the time under the spotlight Google has, with it going public and all, I'd be surprised if this kind of aggressive propaganda eventually doesn't result in a aggressive -although segmentary- outcry against the company.

A group could think the strong focused targetting implied in the ad is racist; or even that leaving people thinking makes google responsible for a climb in the number of accidents on the road : )

After all, it seems logical: The anti-google movement has to become strong, eventually.

And yes, I'm aware of http://www.google-watch.com/ [google-watch.com] .

In the latest issue Dr. Dobbs (you get a free subscription if you attend LinuxWorldConf), they had a pullout job application. It was in the style of an SAT test and was filled with such "oh we're so smart and clever and funny and funky funky fresh" questions such as "write a haiku on database caching" and "the box below is empty. fill it with something" and other questions where any of the questions could be considered correct.

It was really annoying. It didn't make me want to work there at all. It was like a "oh we're so smart mensa+masturbating club".

The point is that if you're really smart enough to figure that out, Google wants to see your resume, and for good reason -- it's probably got some experience doing the kinds of things they care about on it. If you just went to the Google hiring page and skipped the problem, well, they could care less.

Anonymous Coward | about 10 years ago | (#10266208)

spend less time pussy footing about hiring PhDs to pat on the back while MS starts catching them in the search stakes, and spend more time utilising their market share to push :

a) a jabber based IM linked to their gmail sign-in

b) a google browser, or a good set of plugins for firefox

I have had a few searches recently on google which weren't high quality and there are alot of spammers trying to gain attention. Page rank was a breakthrough, and google is still the best, but it wasn't THAT amazing and they need to extend into IM.

Once they have people with an email and IM service linked to a username/pass they have a solid base that will weather with them while they brew up their magic.

They are in a weak position, if another search came in right now which was more powerful... they could lose half their market share in a year. IM and email would halt that by far. And if it's based around open standards I would be cheering them on all the way.

Why? Isn't there enough road rage already? (5, Funny)

IronChefMorimoto (691038) | about 10 years ago | (#10266210)

Does Google not realize what these billboards are going to do? Think of the poor embattled commuters sitting in suburban to urban traffic clog.

Honking at each other.

Bitching on their cell phones about their wives while pissing off the person(s) behind them who are also on their cell phones bitching about the guy that is jabbering on his phone and not moving forward with traffic.

Bumping each other and causing just enough damage to their cars to NOT really want to risk an insurance claim but also enough to want to get it fixed before the neighbors think they drive a shitty car.

Flipping over and killing each other because one of them thought that he/she had to get to work about 30mph faster than everyone else, because that one person has a much busier day of meetings than everyone else on the highway.

Enter Google -- further frustrating drivers with friggin' math problems on billboards. What? You don't think people will look at them enough to be distracted and frustrated at learning that they're not really Google material?

I call bullshit. 'cause that bitch on the uncontested divorce for $299 billboard torments me every day. Not because I don't like my marriage or want a divorce. No -- she begs the question -- "Can you beat me in court if you want the dog and the 50" plasma TV? Eh, buddy?"

Fuck you lady. Fuck you and your uncontested divorce. And fuck Google for teasing me with a job that I probably will have never known existed if it weren't for people that are actually qualified to answer the math problem having posted the g'damned answers here and made feel stupid as shit.

I'd complain more, but this guy behind me in his gas guzzling SUV is honking at me to move forward one car length while we drive past an accident. Thank god for WiFi in the car. If he honks again, I'm threatening him with the Airsoft 9mm I have in the glove compartment.

Google sucks ass anyway (not the search engine, working for the company). If you don't want to move to Mt. View California about the only jobs available at their data centers all over America are hardware managers (ooh - order replacement ide drives...) and data center techs. Google is screwing the hell out the data center techs, luring people into quitting stable jobs for a chance to get in the door at Google - using "contract positions" to build the data centers while leading people into thinking they'll get hired on and can climb their ladder to a sys admin position. If you don't believe, me do a quick monster.com search. Guess what happens when the data centers are built and the techies contracts are up... "Don't do evil" my ass.

scottennis (225462) | about 10 years ago | (#10266258)

. . . unless they figure out this one simple fact:

Math is not English. (Or Math English, if you prefer.)

Language can only be boiled down to equations so far. There always comes a point where subjectivity, ambiguity, irony, nuance or some other non-mathematical factor takes over. And when it does, it takes over in such a big way that the math breaks down and renders all the previous work null and void.

Let me know when they start hiring brilliant people who understand language, then I might be interested in applying.

Besides, everyone knows that poets get more dates than mathematicians.

Anonymous Coward | about 10 years ago | (#10266263)

Is it me or is this kind of question not the stuff of genius. I mean it's just a case of writting a program to brute force the answer. The only leap is figuring out the 49 / sum of digits bit.

Clever maths stuff doesn't (usually) require brute force. Things like the proof of infinite primes and proof of the irrationality of 2^0.5 - now they are clever. Next time I suggest they have a bill board asking for the proof of Goldbach Conjecture [wolfram.com]

Each number is in the digits of e, and each set sums up to 49, so you just need to find the 5th set of numbers in e whose sum is 49.

I was going to submit as a Slashot article, but couldn't find a web site with the questions and I'm too damn lazy to scan them into my own web site. If you search GLAT in google you will find several hits on discussion groups and blogs that discuss it. When I first saw it Google gave no hits on GLAT.

Can be found out using a relatively short Perl script and some math knowledge.

First, find the first 1, 3, 7, or 9 after the first ten digits after the decimal. Take the preceding 9 digits, and run it through a Prime Number Checker. [uiuc.edu] (The algorithm is in the source).

Really, the hardest part is determining the farthest decimal points of e. Here's the formula: limn->infinity (1 + 1/n)n.

It's lazy, impatient, and full of hubris! BTW, I get a finder's fee.

The thing I notice about this is that they've found a way to advertise they have jobs available, and to increase their general branding effort, by paying for a simple banner.

I think that shows a lot more thought than coming up with the equation in the first place.

As for using it to narrow applications to only "smart" applicants, there are a lot of other ways of doing so. Like following up on referrals...
