hmm. based on my experience, I can say that not every team/firm that is hiring would know for the fact as to what is the exact thing the recruit would be doing once on the job. In smaller organizations, there would anyway be lots of confusion on this. Bigger organization, it would be HR drones adding to the incoherence and drama.

So, said simply, "We need folks who are smart and who could get things done. Prior knowledge of alphabus-betabus-gammabus-deltabus --- zettabus would be a definite advantage but is no way a mandatory requirement. Look us up, get to know what we do and if interested, write back so we can talk!" could be one simple template that could be used by just about anyone. Isn't it?
