Need some .Net interview questions

I'd like to think I've been around the block long enough to know if someone is blowing smoke.  I was hoping between myself and our admin (remember we're not 100% ignorant of .Net) we'd know enough to see through the B.S.  If you ask them to 'expand' on an answer, you can usually trip them up.  Don't you think?

I do agree that it would be nice to have an expert or someone here to immediately see through any embellishment and I'm trying to get one but we'll still need the questions.

>>Test for you to fill in:
You actually want to see responses?  

I'll admit that I would only be able to handle a couple of those without some Google time  but I called over our sys admin and he only saw a few he would classify as 'hard'.  He even commented "That's a really good question" a couple of times.

I'll send these over to the person I'm considering bringing in as our expert and see what he thinks.

Oh, I can think of harder questions, if you give me some time to think.  That was questions that floated right off the top of my head, without much thought.

I don't doubt that for a second !!!!!

I don't really want to see the responses, I just didn't want to give you the answers, without you at least thinking them through and seeing how many you can answer without looking anything up.

If you eventually want the answers, I can fill them in as best as I can.

Bob

You might consider a testing service such as BrainBench, http://www.brainbench.com/.

At my company we've used them with some pretty good success.  They provide a useful rating of the answers.

I've taken the C++ and C# tests personally and can testify that they aren't easy.  Looking up the answers taught me a few things.

Bob,
WOW, were you bored?  I'll take a look at the new batch a little later.

josgood,
I'll look into that once we get to the face-to-face interview but I was looking for questions on the tech phone interview.

Those were Google search results that I looked through while I was waiting for a process to finish.

Bob

Thanks again for all the help.

Did you get all 70 answered?

Bob

I had our sys admin scan them.   He seemed to like quite a few of them and seemed to know a lot of them.  I'm sure the ones we don't know, we can research.

I think we can find enough in the list to use and didn't want to leave the question hanging.  I'm afraid, I'd forget to close it out since I'm not active that much.

Thats it, You realy want to kill those poor interviewee , its not it!!!!??  i will never get any .net job within  few years if i get some interviewer like TheLearnedOne!!!!! Joke!!

There is a general interview process that I adhere to, and that is start with easy questions, and see how far you can get until the interviewee starts to squeal, and then back off a little.  *BIG GRIN*

Bob

That is a superset of questions, and you would probably only need to ask a handful to get a good measure of someone's capabilities.

Bob

That's what I was thinking.  If we can get hold of the one senior .Net person that I know about (works in a different division) later, we'll sit down and pick the best and rank them from what we think is easiest to hardest.

I also like to throw in 1 or 2 at the end that will make me go "DAMN" if they can answer it.  Back when I was hiring UNIX admins, I NEVER had anyone answer ALL the questions on our list.  We had the existing group come up with the list and I couldn't even have answered them all.
