Sounds like an ISTP to me, lol. But yes, that's what I'm told. There are times when several different approaches need to be attempted. It's a process. Check this, this, and this...try this...if that doesn't work, then do this...if still nothing then...
you get the point, lol. And that is just fixing a problem. IT people usually know what they are doing while they are doing it. Tests usually aren't their thing. Put whatever you want them to do in front of them and they can show you lol.
