Hi Esther.  IMHO one of the biggest mistakes a hiring manager can make is 
to filter out candidates on the basis of certifications, at least for 
senior positions.  Granted if they are flooded with applications they may 
use this as a means of reducing the number of resumes to a managable 
number.

I'm afraid I have found HR departments filter out a lot of good people for 
questionable reasons.  I think they just don't understand technical 
resumes and simply get it wrong.

I've seen this happen as a member of interview panels - I know the resumes 
handed to me for a senior position can't be the best people who applied.

On the plus side this seems to be less of a problem than it was 5-10 years 
ago.

In a real situation I ask a combination of technical and non-technical 
questions but if I have to choose _one_ I'll make it a technical question:

* Describe a TCP 3-way handshake to me.

This is one of the stock questions I always ask in interviews.

Really everyone going for a technical position today should get this right 
but they don't.

Seriously... the network really is the computer

Rule #1: *Understand* networking at each layer.
