Interview questions gone wrong...
-
Had an interview over the phone today. Totally bunged the question. They asked for a test to check if a number is a power of 2 and I answered it as a test to see if it was divisible by 2! Should have been (x && !(x & (x - 1))). What a dolt I be! I was so nervous I messed up other simple ones too. Needless to say I didn't get the job failing the technical questions. Anyone have other mixed up interview questions?

I wouldn't have gotten that either. :doh: I'll have to remember it.

x % 2 == 0is probably what they were expecting. Good luck! Alvaro
If [God] knows what we are going to do then we have no free will and are just characters in a play written by him. Without free will, morality for humans makes no sense. Without free will and morality, any sort of punishment or reward system loses any justification. Heaven and hell would be places where [God] could watch the souls he created, predestined just for eternal happiness or agony. - Mark Thomas

:confused: How will that help determine if a number is a power of 2? Powers of 2 are 1,2,4,8,16,32...

New Dawn EngineeringIf that is of some comfort to you: I screwed up a simple binary search in an interview once.

My answer would have been, why are you testing to see if a number is a power of 2?

I think, anyone that asks me to interview, I would say, "um, thanks, but I'd rather interview YOU and YOUR programmers" which I've done, not explicitly, but most people don't know how to interview, and it is SO easy to get them to talk about themselves. And programmers of course love to complain, so the "what do you like about this job, and what do you hate about it" is an awesome interviewee question. ;) Marc

Easy, for mathematical factorization like Mersenne primes. You change your algorithm if it is a power of two +/-1.

New Dawn EngineeringI guess it sort of depends on the type of programming you will be doing, but seriously, folks, when was the last time you had to do that in a program? I've been writing code for 25 years. I'll be polite: this is a bs question. If someone asked me that question over the phone, I'd have a hard time not laughing. I think I would respond with, "could you give me an example of actually using such a silly question?" Am I the only one here thinking this?

Oops, perhaps he meant multiple of 2. :-O At least, that's what I understood. :~ Alvaro

New Dawn EngineeringMan, all my recent interviews have been what are your strengths/weakneses? I actually had one guy who admitted he hadn't interviewed anyone in about 5 year. So I got out of tought questions. (Man I wish those guys would call me back with an offer!) :badger:

i like that wanky one about biggest weakness - i give them the "oh you mean hwo i always work too hard" with the eyerolling and p*ss takign then i tell them that my biggest weakness is that i tend to speak my mind. "why is that a weakness?" "because sometimes i don't bother preparsing it, so if you don't want to hear what i have to say, dont hire me" works well in nz, australia and the UK though Dunno how that would go down in america land- but i'm not in Amexica ;) - suspect i might get away with it coz i'm not a local Bryce

Whatever it was meant for, unless you are un-employed, you'ld be happy not to work for them: I can't see how can be so important the ability to determine if a number is the power of two; I can find tons of sample in dozens of languages just goggling, if I ever needed it. In my opinion, the most important thing in a developer is not how to solve such a small problem, but how to properly design an application, so that it's stable, easy to correct and expand and possibly performant (but this may vary, depending on the target). Looks like yor interviewer is (or was) a coder, not a programmer. Good luck for next time!

I would only see it being valid if it was for something along the lines of game programing or some sort of math intinsive software.
