Shoot - SCORE!!!

Allow me to modify Gresham's Law. Where hiring managers can't tell the difference, bad programmers drive out the good.
Admin
Why is Omar being upset with obviose perfect candidate for job?
Admin
Outsoursing company story sound fishie to me.
Admin
If I were hiring and training my replacement I would most certainly go after the person that is least capable of being my replacement.

Andrew must not have ever met any Southerners before. I think the candidate sounded very enthusiatic given the context.

TRWTF is an ORA-1555 error
Admin
Hey, I've never met an android. Except for repeating memorized sentences, what was he like? Could you tell any other difference from a human? Did he display emotions?
By the way, TRWTF is Oracle. The company. Or worse yet, its clients.
Admin
Waitaminnit, something fishy here. Even Alex can't screw up the English language that bad.
Nagesh, are you writing for Alex now?
Admin
Whatever happened to TopCod3r I miss him
Admin
Ooops! Sorry about that, folks. I think I forgot to re-enable the subtlety module. NageshScript has been writing for Dane Cook recently.
Admin
Well, to be honest, HTML really is more limiting that Java or C.
Admin
The one time that happened to me the company had already taken care of that prior to the interview stage. IIRC within a year of that their gross value went from 14 million to 3.5 million.

5 weights in 3 weighings? That doesn't require any level of brain power. Isn't the question 8 in 2 weighings?
Admin
Admin
IF YOU HAVE A BOX WITH THREE LIGHTBULBS... I'd answer "I 'd have something smarter than you"
Admin
I happen to agree. SI ought to include non-PC hardware (such as cash registers, weighing machines, bar-code readers), training employees, connecting to existing company finance, sales, and logistics processes, roll-out planning, help-desk setup, on top of a new application and a new DB. Otherwise it's too easy - there's not much of a challenge in that syllabus.
And what's with the Networking modules being about Residential? Where's the scale issues that apply in the business environment?
Admin
LOL, it's funny because he has an accent!
Admin
Racism, huh? I don't think I saw any mention of the interviewee's race. But yes, it's funny because he has an accent.

Admin
I'm not sure he is black. He said "jarva", not purkles.
Captcha: acsi - how black people say ASCII.

I'd once gotten a job request from a recruiter with the position specifications lifted right off my resume word for word. I'd worked there previously and someone found my resume on Dice and sent it to the recruiter for a job spec. I think they went through 3 different people in less than 6 months. The best part of that was my new job got one of the rejects. He left off his brief stay at my former job where he spent most of his time chatting on the phone and decided to substitute some other company. I'd even met him over lunch with my former cow-orkers[1] a few months back.
I wouldn't have recognized his name had he not put down 19 years of SQL server experience (this was 2007), 20 years of Oracle experience as well as DB2 and IMS experience.
His resume was about 20 pages, nothing in the last 10 years over 3 months. Since this was a work-at-home position, I might have gotten some work out of him as long as he didn't have unlimited calling but I wasn't interested in finding out.
[1] Deliberate misspelling for the SpellingNazis(tm).

He tried the cortical stimulators, but there was no response....

The general solution for N weights is CEIL(N / 3) weighings, so 5 weights would need 2 weighings, and 8 would need 3.
Admin
Because the level of troll has gone downhill so much since he/she went missing. Used to love watching Topc0d3r say something really dumb to bait everyone.
Nagesh is the closest thing we have now, but that's not even really close.
CAPTCHA: capio - I had to capio the audience with stories of yore.
Admin
I'm assuming I'm misinterpreting the question, but if you have five weights wherein 4 are the same and 1 is different, but they are visually identical, then how can you possibly detect the different one (for sure, under all 5 possible cases of which one is different) without at least weighing all five at least once?
Or does it mean comparative weightings i.e. using a scale (thus checking two weights at once)?
Admin

AdamJS: Assume you are using a balance for comparative measurements.
Admin
It's possible to sort out 12 weights within 3 weighings. You can also decide whether the odd weight out is heavy or light within those three. (It's usually called the 12 coins problem, for googling.)
Admin
Admin
It can be done in 4 measurements without any assumptions, and 3 if you know whether the odd one out is heavier or lighter.
It can also be done with 3 if a comparative scale is used.
Admin
Amateurs! With the proper device, you only need to make one measurement.

Whenever I see someone bring up that lightbulb puzzle, I feel compelled to point out that the puzzle itself is fundamentally broken.
The normal assumption in a puzzle is that all the components are ideal, because the story is really just window-dressing on an ABSTRACT puzzle. If something is in an opaque box, you can't peek through a crack. If something has an on/off switch, you can't hold it in some middle position that makes intermittent contact. If you don't make those kinds of assumptions, these puzzles generally have a huge number of possible solutions, most of which are uninteresting and rely on circumstances not specified in the problem statement.
The accepted solution of the lightbulb puzzle is to check the temperature of the bulbs. But that relies on an arbitrary non-ideal assumption (non-negligible waste heat) that isn't stated in the problem, so that's no more legitimate an answer than "I peek through a crack in the box" or "I trace the wires to see what's connected to what". It's arguably not even a REASONABLE assumption these days--what if the lights are LEDs?
Lateral thinking puzzles don't generally belong in interviews, but that particular puzzle doesn't even belong in a game of puzzles. If you got the "correct" answer without being told, that actually means you're WORSE at these puzzles than many of the people who didn't get it, because under the normal implicit rules, it doesn't have a solution.
I imagine that puzzle has many permutations depending on the exact nature of the measurement tool you use and whether you are told in advance that the different weight is lighter or heavier or only that it is "different".8 is likely a popular number because it is a power of 2, and therefore adds an extra red herring to the puzzle.
Admin
Oh, so you haven't died in a fire yet. Well, there's always tomorrow.
Admin
The point of the light bulb puzzle is that it is best to go down the path of least resistance first. Maybe the bulbs do not put out heat, but given that most do, it is an option with a high probability of success.
I'm more interested in someone who will troubleshoot through experimentation and observation, and who will not be more interested in the elegance or cleverness of the solution than in solving the problem at hand.
Admin
I hate dickheads who think it's important to know what error numbers correspond to what error off the top of your head - there is no reason to know which number a particular error is, there is very much reason to understand what a particular error is (and Oracle provides functionality to see the actual error message to this end).
Admin
Admin
Would also work for 9....

Admin
You obviously haven't dealt with Oracle before. Work with anything more than a toy database, and you'll learn to hate certain numbers with a passion. They will haunt your dreams and possess your soul.

What SI is and isn't in real life is irrelevant (in the context). The candidate was relating to the interviewer a course he studied called Systems Integration. Whether that course actually taught Systems Integration as advertised is totally irrelevant, and the interviewer is merely being a knob-jockey by challenging the candidate.

It is still a fundamentally broken puzzle - it relies on assumptions about particular light bulbs (yes the most common type, but alternatives are readily available and that common type is approaching a rapid decline). While most candidates will have had some experience with a heated bulb (who hasn't changed a light bulb just after turning it off, or tried while it was still on), slim few are going to make the required leap to the assumption made by the puzzle to make it solvable.
There are plenty of other puzzles which don't have some catch to them from which the puzzle draws assumptions and requires familiarity with the catch to solve.

Puzzles... One time when I was in an airport lounge, I noticed a math teacher giving quizzes to his group of students. Being the helpful type, I answered them before he could get the whole puzzle out. It felt real good for me (a bystander) and you could see the math teacher fuming that I knew the answers. The two puzzles were: You have a bunch of socks in a drawer, (usually 10 black, and 10 brown), how many socks does it take to get a proper pair to wear. Answer: 3. A tree is dropping leaves as the season progresses. Each day it drops twice as many as the day before. Assuming that it always drops the maximum numbe, on which day do most of the leaves drop. Answer: last day.
I was smiling as I went to the plane.
