One of my job postings, I got over 100 applications. Most people weren't even tangentially related. They were spraying and praying. Worse yet, I had to screen everything by hand. A rather tedious job and made worse by Taleo. And as much I understand why people don't want AI screening and my company strictly prohibits it - by the end I was begging for one.
Finally, not even one application was matching the job profile and many had used AI to misrepresent their skill.
My company has a policy that once a position has to be opened, I need to fill it within 6 months. So, fed up I had to work with HR to message people on Linkedin.
This has basically dissuaded me using the spray and pray or AI generated resumes, if and when I start my job hunt.
