That's mostly been my experience as well... That said, there always seems to be something wrong on a technical response and it's up to you to figure out what.

It has been relatively good for writing out custom cover letters for jobs though... I created an "extended" markdown file with everything I would put into a resume and more going back a few decades and it does a decent job of it. Now, if only I could convince every company on earth to move away from Workday, god I hate that site, and there's no way to get a resume to submit clean/correctly. Not to mention, they can't manage to just have one profile for you and your job history to copy from instead of a separate one for each client.
