Anyone in any field from music to engineering to sports to medicine who cannot
perform on demand is not a professional.
Early in my interviewing career, I had a reputation for being "intimidating"
and was advised to dial it back a notch.
I may have over-reacted and gone too far the other way. :)
In my youth, I played sport at an elite level and earned an unfortunate
reputation as a "choker" under pressure -- several sessions with a
Sports Psychologist made a huge difference and I was eventually able
to shake the "choker" tag and perform well under intense pressure.
Though I have no experience in entertainment, I imagine musicians similarly
experience intense nerves before stepping onto the stage.
Ditto for Surgeons; if they make a mistake their patient dies --
maybe they get used to it, I don't know, though my sister-in-law nurse
claims they're all on
I'm not convinced though that the average computer programmer needs to be able
withstand that sort of pressure, at least I've never experienced it at work
... though I'm told Yahoo was a pressure-cooker of a workplace a few years back. :)
Anyway, thanks for the heads up, maybe I need to readjust my interviewing
technique, again, this time putting the applicant under a bit more pressure.
BTW, I heard an anecdote that during interviews at Microsoft, the interviewers
sometimes "staged" a ferocious argument in order to test how the candidate
reacted to extreme pressure and conflict. :)
