I worked for a company that kept one job posting open for more than 4 years. They've used it to hire more than 100 people, but unless you worked there you wouldn't know.
Not too surprising. I've been at companies where a job posting is hyper-specific to one job description, as soon as I (as a hiring manager) change a single word, HR makes a new job posting and cancels the old one.
And also I've been in places like you describe, where one generic "Software Engineer" job posting is reused to hire many people into many teams, since they're all "Software Engineers" so they just recycle the same posting for everyone.
Funny enough, on a local glassdoor clone the guys who failed technical interview discussed exactly this possibility precisely because the post was open for so long:)
I used to joke about creating spray on mud as my million dollar product idea. Macho up your suburban assault vehicle with some many mud splatters without getting your hands dirty.
I see a lot of very well waxed and polished "off-road" vehicles in the nearby smallish city.
I've never seen a rolling coal lifted pickup on a forest road. Actually looking dirty is not part of their aesthetic.
Yours truly, former owner of a ridiculously lifted jeep that's been all over the western half of the US and regularly went up & down dry creek beds with 1+ foot vertical drops/climbs that needed the clearance. That thing never saw a clean day. Hose it until there's no longer mud on the door handles.
