If a tech company can't even do basic math — or rather, openly cares so little about accuracy — does that sound like a place you would want to work though?
The recruiters who make these boneheaded mistakes are typically organizationally separate from the actual engineering group you'd be working in.
this sort of thing happens more often at larger non-tech enterprises, or places that have a type of "software team" that is not the main focus of the org.
