Interview Questions

I don't think that deductive thinking/troubleshooting can be taught - it is an inate ability that someone either has or doesn't have.  When I meet with potential job candidates, I try to determine if they have this ability.  

Job-specifics like IOS commands can be taught to just about anyone.  The ability to know when to use those commands can not :-)

On my second-ever IT job interview (waaaay back in '98) I was asked to explain how a 4-stroke internal combustion engine worked.  I got that job...

KISS - keep it simple stupid.  Start with the easy stuff to check, assuming nothing.  If you're looking at a network problem, work from the bottom of the OSI model up.  If you don't know the OSI model, learn it.

It would help us help you if you told us what your background is and what kind of IT job you're trying to get ... "IT jobs" is pretty vague, and you'd get better information out if you put better info in (another IT principle - GIGO - garbage in, garbage out).

More info:
I was employed as Network Admin at a local bank.  I am interviewing for the same types of position.  I have interviewed with two companies for field engineers and then this last position was for an IT specialist position supporting users over the phone and in person.

All of the current suggestions are very good.  Any additional would be appreciated.

I used to ask all sorts of interview questions, depending on what the client I was working for was hiring for or wanted to see in a candidate.  Sometimes, the most interesting response can be found by asking questions outside the domain of the hire.  For example, asking a manager candidate the difference between 802.1q and the cisco version of this protocol.  Or asking an engineer candidate to discuss project budgets.  This can give you a very clear and fast picture of either limitations of hidden abilities.  Sometimes.  Sometimes it just upsets the candidate :) (also useful).  I often ask detail nitty-gritty questions, like

What is the purpose of SNAP in ethernet packeting?
What technologies use Token Bus as an architecture?
If an adapter card is using RAM between paragraph D000-D3FF, how much space is that?
How do you propagate default route?
How big is the IPX network number in Octets?
Compare NTFS to FAT16.
Whats the appropriate mask for 10.6.5.81 if you use a natural mask?
Using the same address, what address is the router at if I tell you the router is the first available address on the network?
same question, but instead of a natural mask, assume the the network is divided to allow a max of 14 workstations on a single network?

Then we ask about protocols, and NOS and directory permissions....and if they are still standing, I hire them :)

JonSH: about the subnetting questions, do you give them paper and pencil or expect them to immediatly know it off the top of their head? The first two don't have much to work out, you either know them or you don't, but the third one even I would need some paper (or at least a few minnutes of quiet) to work out and I think I know subnetting pretty well.

samccarthy: What are the 6 troubleshooting steps? and, what does it mean to "ask for the job"? I've heard alot of people say to do that, but don't know how to actually do it. Do you just say at the end of the interview "so, can I have the job?" and wait for an answer?
