http://www.npr.org/features/feature.php?wfId=3916173 All the info you need for this puzzle is in this link. Apparently Google is looking for engineers and has set a series of puzzles for job-hunters to attempt. The 1st puzzle is to go to the website http://www.{first 10-digit prime found in consecutive digits of e}.com Good luck!

that was rather easy.. Of course the first answer can be easily found through google And the second using the integer sequence database you all should know how to find.. And that's it allready, apparantly..

That sequence is in a integer sequence database? We probably don't have the same solutions.

That second puzzle is a real stinker! It was only when I was checking divisibility that I stumbled on the first necessary insight. It was pure luck that I guessed the connection with the first puzzle. You can use a string containing the digits of e to solve both puzzles; I found this one containing a little over five million digits! http://antwrp.gsfc.nasa.gov/htmltest/gifcity/e.5mil

Someone asked whether it is the HR or PR of Google who published the puzzle. The puzzle is so easy (it doesn't even require a fast primality test) that it must be the PR. It is just a way to tell people that Google is a smart company that hires smart people. I don't think it makes a difference, when you send your resume, whether you solved it or not.

A friend of mine sent me the following link (quite new): Google Working to Recruit Brainy Elite It mentions some questions already discussed in this thread. What was more interesting for me, is the paragraph on 21-question aptitude test. It includes the question about 2-dimensional lattice of resistors, posted here by THUD&BLUNDER in the easy section. I just wonder: how many of 2,700 google workers are capable of solving this by themselves?

MathWorld published a detailed analysis of the original questions and some of the aptitude test questions: http://mathworld.wolfram.com/news/2004-10-13/google/ The answer to the resistor problem is published (#10). I almost kicked myself when I saw how easy it was and now I wonder why I couldn't answer it when T&B posted it here!

| I noticed that MathWorld put their analysis online at Oct 13. THUD&BLUNDER put the following 2 problems two days later: Resistors Next Number? THUD&BLUNDER, are you working for Mr. Wolfram? And now I am really afraid he will execute me...

Sorry about that, guys. I didn't read the question properly and didn't know the answer when I posted. on Nov 1st, 2004, 11:42pm, Barukh wrote: And now I am really afraid he will execute me... |
