I agree with that in principle. But...

Recruiters and hiring managers *are* hobgoblins with with little minds. 
And definitely not PEP8-complaint. :)

When I was out of work for two years (2009-10), underemployed for six 
months (working 20 hours per month), and filed for Chapter Seven 
bankruptcy in 2011, I  only had 20 job interviews during that time. That 
was a learning experience. I did everything possible to present myself 
and my resume as perfectly as possible. When I had another bout of 
unemployment that lasted eight months (2013-14), I had 60 job interviews 
and three job offers to pick from at the end. Of course, that was for IT 
support contracts. Maybe programming jobs will have fewer hobgoblins.

Thank you,

Chris R.

Do you think that recruiters and hiring managers read your code at all, let
alone that they read it will an eye to PEP 8 compliance?

No recruiter[1] will do this. No recruiter will even know what PEP 8 is.
They're looking for technical buzzwords ("ten years experience with
Django"), they aren't qualified to judge whether your Django code is good,
bad or indifferent. That's up to the client.

A hiring manager with a technical background might, once you are in
consideration for the job. More likely they will delegate any judgement to
a technical manager, or programmer, who may or may not be a hobgoblin with
a little mind. There are plenty of programmers who are obsessive about
following PEP 8 even when it makes the code worse:

    mywidget.component['key'] = (mywidget.grippley.count_item(spam or eggs)
                                 + 1)


(I've met plenty of technical people who are opinionated and badly informed,
not just managers. Just last week, I was told by one programmer that
Mersenne Twister, the default RNG used by Python, is well-known to be
biased, and that "everybody knows" not to use it to choose an item from a
list because it is documented "everywhere" as being more likely to choose
the first or the last item than any of the others.)







[1] Sweeping generalisation. In a world of 7 billion people, there's
probably one or two exceptions somewhere.

I meant more than a few technical professionals who got pushed out of 
the job to become recruiters. They tend to ask about everything on the 
resume to poke holes where they can. Each time I tightened the wording 
of my resume whenever they exposed something. If I posted a GitHub link 
on my resume, they *would* check it out. If they know Python, they 
*would* run it.

As for PEP 8 compliance, it was a joke (see the smiley). Laugh, it was 
funny.

When I used to apply to Linux system admin jobs, the recruiters would 
have a checklist box for the "Red Hat GUI Thing" as an absolute 
requirement. My Linux work experience was exclusively remote command 
line. On the rare occasions that I have used the Linux GUI, I always 
used what got installed as the default GUI for Fedora or Mint.

The first time I said I didn't know what the "Red Hat GUI Thing" was and 
explained that I was fast learner, the recruiter hung up on me. I tried 
to argue with other recruiters that I knew the command line equivalent 
for the GUI. No dice. Some recruiters even accused me of making up 
techno-babble. They all hung up on me. After a dozen phone calls like 
that (all for positions at different companies), I generally stopped 
applying to Linux jobs.

This year I built an inexpensive PC to run Linux and installed the 
current Red Hat Linux. Guess what? The "Red Hat GUI Thing" wasn't 
installed. In fact, the GUI was Gnome by default. According to my 
coworkers, Red Hat started phasing out their own branded GUI several 
years ago. I guess the recruiters haven't gotten the memo yet, as I had 
a phone call about the "Red Hat GUI Thing" last year.

Every hiring manager I've ever interviewed with had a technical 
background. The only exception was when the final interview was with the 
marketing director at hardware company. I declined to take the job. If 
you know your Dilbert, it's bad luck when a hardware company is run by 
the marketing department. I wasn't surprised that the company filed 
bankruptcy a few years later.

Thank you,
