First, a little bit of legal house keeping: The views I am about to post are not necessarily those of my employer.

Having just done a batch of interviews (Yes, we're hiring), if your interviewing at a shop that does technology X, please be familiar with technology X.  Being able to spell that there "c pound" language does not give you the right to put it on your resume.

Oh, and please, if your going to come interview with us, at least know what an interface is in the context of programming languages, such as C# or Java.

That is all.
