Great stuff!!!
Also, this bumps me down to "where I know I belong." I'm now a 7.5ish --
not an 8.5ish. And, that's more realistic. I think everyone wants to be in
the "10 category" just because it's the highest. But, if we don't make room
for such things, we'll not have anywhere to grow.
I will be consolidating more and be using this as a personal rating scale
-- and also, as a somewhat objective way to judge the skill-set for new
developers.
And, frankly, how much simpler would it be to give a list like this to a
recruiter, company and or developer. A developer won't be able to fake
being in a higher category than he is. A company is generally pretty
flexible in their role (i.e., we'll take a 4/5 for our junior position; a 6
for our regular positions; but the higher the better). 90% of the
mismatches from recruiters could be cut down if we just handed this scale
out and asked to self evaluate. (Or, I'm being naive?).
I love it. Keep it coming :)
Cheers,
Glen
