Why would some companies advertise a job post as Software Engineer, and only to find out deep in the process after doing multiple interviews, that it’s actually a support job??

Seriously why the fuck do that? That’s disingenuous and misleading as fuck?
And why would a dev be dropping a dev job and experience to do tech support ? Is it even worth it?

Even if it is, can you easily switch back to an actual dev job afterwards?
Wow the things some of these companies do 😶🙄😑🤦🏾‍♂️
