Sam,

This posting has provoked far more responses than perhaps it requires.

I'll assume from the grammar and the surname that English is not
your first language, and allow for that.

Well, all I do is program the PIC16C65 all day but if this were the only
skill I had then it would be hard to get any other job.

Skills cross-pollinate and blossom in novel ways.
Appreciating both hardware and software allows you
to design each with the other in mind.
My technical authoring skills allow me to prepare
project proposals and technical reports well.
A hobby interest in astronomy and satellites got me a job
offer with a company writing satellite mission control
software.

Regarding fluent English, this is essential if you wish to work
with English-speaking engineers. I certainly would find it
extremely hard to work in say France without being fluent in French.

Regarding spelling, an occasional slip of the finger is forgivable,
but when people repeatedly mis-spell the same word it is obvious they
don't know how to spell it. Acceptable for those learning a language,
but not for native speakers. If someone is not able to spell in their
own language, or is too sloppy to care about details, then I would
not employ them to produce good quality work. The comment about
mis-spelt variable names holds true.

Learn as many skills as your ability allows.
Each is a potential meal ticket!
