Jeff and .NET

Personally I find it a little overkill.  I have been programming for a while and ran in to one of these interviews and froze.  I knew every single answer, but froze.  It was quite frustrating.  They passed on me and I ended up getting a better position makine more money churning out better code.

Here's the modulus in action btw.

for (int i = 1; i <= 100; i++)

           {

               if ((i % 3) == 0 && (i % 5) == 0)

               {

                   Console.WriteLine("FizzBuzz");

               }

               else if ((i % 3) == 0)

               {

                   Console.WriteLine("Fizz");

               }

               else if ((i % 5) == 0)

               {

                   Console.WriteLine("Buzz");

               }

               else

               {

                   Console.WriteLine(i);

               }

           }

           Console.ReadLine();

I've had to use it several times.  In one case I was reducing fractions and needed the greatest common denominator.  :-)

I couldn't agree more.  I just recently added a blog entry on how the Transcender tests are absolute rubbish for trying to determine the skills a developer has.  30% of the test was on DataSets.  WTF.  I use DataSets about once in every project.  

I also don't think the ability to snap off the definition of polymorphism means you can code anything worthwhile.

I agree that there are a lot of developers out there who don't know how to write an if statement to save their lives.  On the other hand, it depends what you're looking for.  At my company we a lot of work with datasets.  We used to be a complete oracle shop with forms and reports, and have now started working with .net, however, most of our code is in packages and procedure.  We don't need any developers who have no idea about what a dataset is or have no clue how to write objects on the database.  That's development too!  I don't see how you can be a developer without knowing what the big picture is. Answering that you don't know anything about datasets because you use container objects and generics sounds impressive, it also sounds like you have no interest in expanding your horizons and learn what happens to your data.

Yes Jeff, that is exactly what I told them.  DataSets, while improved in .NET 2.0, are expensive containers that developers over-use all the time.  

I'd much stick with throwing around Objects/Object Collections accross my tiers.

I cannot believe that self-proclaimed senior .NET devs would not even know about the modulo function.

Granted, some may not know the exact operator off the top of their head but should at least be able to write psuedo code with modulo in it.

Also - senior devs (8-10+ years experience) who say they haven't used recursion? I do find that hard to believe.

Call it what you want. I've interviewed them too.

I don't think the test is about the modulo function. It's about solving a challenge. I'm confident that you could write a simple function which checked if a number is evenly divisible by 3, right?

Jon - well ofcourse, but wouldn't you assume experienced developers would at least be aware of what the modulo function does!?!

coding is one of the most complex part of programming. you need to devote yourself, like you need to be connected emotionally otherwise you'll fukk everything up. my advice is to take your time and be yourself and dance with the code. LOL

//There are two types of programmers:

[Flags]

enum ProgrammerTypes

{

 ExamPassers = 1,

 SuccessfulExperienced = 2,

 Both = (ExamPassers | SuccessfulExperienced)

}

//The only one that really matters is the second bit.

I've worked in companies that have hired total duds, you're playing with fire if you don't ask these kinda questions.

You've never used to mod operator in C# (or any related language)? We were just talking about this the other day at work...sure you can almost always find a different solution, but never a rarely a better one. That's like saying you never used the multiple operator 'cuz you only bothered to understand the addition operator.

For first job out of college I got grilled with SQL/PHP questions. I had a couple friends apply and did not know any answer and still got the job. The only difference between answering the questions correctly and not is the pay...I guess the price was $10,000 more for correct answers. Where do they calculate this crap...

I've used the mod operator a couple times ( 2 or 3), I've been using C# and .Net full time for the last 4 years.

I really don't find that it comes up very often, even though I read the C# spec when it was publiched, I still needed to look up the operator the first time I was going to use it.

Actually... the question was not about the mod operator - it was about printing Fizz or Buzz (or FizzBuzz) at the appropriate time. You do not need to know about the mod operator to do this -- it is just most obvious approach.  FizzBuff is designed to test if you can think rather than if you know a fact.
