I'm currently advertising (Craigslist) for an embedded-systems
programmer. The ad asks for "something like a resume" and a code
sample. Got lots of florid resumes, but only a few people (out of
close to 100) actually submitted code samples, and only one was a
decent, readable hunk of code. Pitiful. Would you hire an artist who
refuses to show you any of his work?
Have you listed the salary as well?
No. It would vary a lot, depending on the person.
Not a lot. You already made up the number in your head, and you know
exactly the type of the person that you need.
If I hire a talented
kid with little experience, and spend a lot of time on speculative
training, I'd pay less than for someone that I knew was going to be
very productive right away. I know a few people like that, but they're
not available for hire right now. Hell, I'd give them a piece of the
company.
Quit telling stories and playing games. Each thing in this world has the
price.
Would the decent engineer work for this salary?
A good embedded systems programmer would make as much as a good
engineer. Both should contribute about equal value. If a programmer
working one hour saves me or another design engineer one hour (I
wish!) then s/he'd be pretty valuable.
Would you bother for someone who refuses to show the money or who wants
something for nothing?
What are you raving about?
You are complaining that your ad is attracting only riff-raff. I am just
trying to explain why.
We have excellent pay and benefits, as the
ad notes.
That tells no information.
Nobody here works for nothing. Most hiring involves
evaluation and negotiation on both sides.
And, incidentally, about 100 people did bother. Maybe 4 or 5 are worth
interviewing.
Such a poor result is not because the world is pitiful, but because this
is the expected response to your request.

Good point. He knows I'd never hire him. Far too rigid and far too
willing to reach firm conclusions on inadequate evidence. Dangerous.

John L, Methinks you need to revisit the original SOW, before
throwing stones...
"I'm ok with fixing and adapting circuits but not so good with design.
I've come up with an electronic switch circuit but I think it could
use improvement. The goal is to turn on a 12v relay with a switch
that is closed when off and open when on. The switch also has to have
one leg grounded. It's a pressure switch with a single terminal. I
also want the relay to stay closed (on) for a couple minutes when the
switch goes from on (open) to off (closed). Here's what I've got now
and it does work. But I had to use a pretty big capacitor and I'm
still only getting about a minute of delay when going to the off
state. Because I can't make the 10k resistor any bigger. I'm
thinking that it is likely possible to get a longer delay and do it
with a smaller capacitor if I was better at designing this. The other
flaw is that this slowly lowers the voltage to the relay until it
drops. The relay stays pulled to about 3 to 4 volts. I also suspect
there is a better way to keep it fully on until the rc timer expires.
Thanks in advance for any suggestions
