When it comes to the tech industry, I stereotypically expect it to be staffed by unconventional professionals. Long hair and grubby nails offset by a technical knowledge and attention to detail.
Unfortunately we often get the long hair and grubby nails, and very little technical knowledge. Give you an example - called up UK2 who host our business website and told them we were wanting to try out Google Apps, which basically meant changing the MX records to point to Google.
I'm not a great pro at these things, so I called up their tech number and got a laid back American, who sounded like a teenager (this is a UK support line) - he was completely useless. Told me all sort of nonsense to try and get me off the phone because he obviously had no idea what to do, he did do a good job of trying to sound clever. I gave him about 5 or 6 minutes to have a go and look through his online tutorial
Then I got impatient and told him what I thought of him and to transfer my call. The next guy was down to earth and sorted it in a minute, easy peasy. Over £1 a minute to listen to that nonsense
Need to face it - most industries now are full of useless, untrained and untalented 'professionals'. You're best of informing yourself, I try to learn as much as I can about any problem before getting help on it.
It does feel great when you occasionally meet someone who really knows what they're talking about and sorts the problem for you instead of fobbing you off. But that's rare in my experience these days.
