Does it really gauge one's ability to code ?

This is basic programming stuff. They want to see if you can do the math. Do you know what the answer is?

I did an IKM assessment for C# and some of the questions are so odd it makes one wonder does it really gauge one's ability to code ? You are given a program and 5 outputs and you have to choose right one. One of the question was what is the value of x after running this code ?
int x=0x0000FFFF; x=x>>4; x=x<<4; x=x|0x0000000F; x=x^0x55555555;Where in real world application am I going to use this ? I scored 76 out of 100. Last time I took .NET 4.5 test I scored 88. How does it help someone understand my ability to write code for actual application ?

Specifically: Well, you get to look at it with a bit of perspective : Rshift followed by Lshift of the same amount simply introduces as much zeroes as in the the shift on the right of your initial number. This means the first three operations neutralize in this case. So you simply XOR the last four 5 with F, which gives A (A5 pattern is commonly used to test memory, since both are made up of alternating 0 and 1's, that are swapped when XORed with F, so result of F-XORed A5 is always 5A). More generally: This is testing your logic, and how you can use your brain to solve something. You will probably never use it if you do not do low level, but sometimes it helps to solve complex situations to have a analytic mind.

Your question, young Padawan, tells me that close to the hardware you programmed have not yet. Look at a processor's instruction set you must and such logical instructions find you will. Learn to use them and address calculations and bit masking you fear must not. :-)

I haven't personally seen any (production) .Net code that uses shift left/right, but its use was somewhat frequent in some unmanaged C++ code I've been involved with.

As soon as you leave the beaten path of serializing/deserializing from and to XML, you will have to do a good share of bit twisting.

Knowing how to code C# syntactically, doesn't mean shit in the real world, in and of itself. I am more interested that my fellow engineers know how to solve complex problems, and you can't really take a fucking test for that, now can you. I am strongly against organized testing, as I have seen it prove nothing really, time and time again. We have fired more Engineers from our shop because they could not design, let alone implement, basic problem solving solutions, versus their ability to do basic C# fundamental tasks (you can learn this shit, duh). I don't think you can learn problem solving, I think you are born with that - true problem solving. In summary, syntax and code fundamentals you can learn (if they are not retarded), but problem solving is hereditary. I am more interested in one's ability to problem solve, then the proper way to concatenate a bloody string

This misnomer is by design, because I am anything but a slacker, thus, the reason I chose this to be my online name. I also like James Bond films, and I am not bad-ass enough to be a super spy, so I threw in the "007" for good measure.

That's one of those question that make it clear that the recruiter (or whoever is interested in your score) has no idea what to ask so he makes up artificial challenges. It doesn't matter at all if you can clearly predict the outcome of code that wouldn't pass a code review.

Somebody who is good in bit-shifting isnt long-term qualified for the stupidity and annoyance C# and XAML. :~
Press F1 for help or google it. Greetings from Germany
Don't see what XAML has to do with it. I write C# to interface with hardware, do a lot of bit manipulation, and I've never used XAML in my life.

Not that I don't know how, it's just been over 10 years since I last had to do bit shifting. No doubt someone fresh from college would do it off the top of their head because it's only been 6 months for them and would give them an advantage in test conditions.

This question tests your ability to use the bit-manipulation operators. You would use such code when writing comms protocols or device drivers, and lots of other places. If you haven't seen code that does a lot of bit manipulation, maybe your experience, and thus your mastery of C#, isn't as great as you thought it was.

If you are writing a general ledger then no, it's not that relevant other than demonstrating a basic knowledge of boolean algebra and numerical anaysis (i.e. truncation and how it affects accuracy). If the job was embedded, especially bare iron, it's a core competency and if you missed it you better go back to selling shoes on a website. Any time you interface to a foreign app or device it's quite likely you'll come across situations like that. Even if it's C#, when you build that production line tester that interfaces to scales, spectrometers and time of flight sensors you'll have to know boolean operations. And if you don't understand boolean operations, how do you build SQL queries or LINQ statements?????

Indeed. Lines 2-4 are obsolete. How inefficient! ;P
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
