My company sometimes uses that too. It has your general keyword filtering on resumes, with sensitivity adjustments.
It also has a tool to ask questions, then candidates video record themselves responding (as many retakes as they want) and the hiring manager can review their video so they aren't bound by a mutual schedule. No AI element to that (yet) that I'm aware of, but could see the potential to screen the videos through an AI filter.
I don't like the video screening, personally. Neither as an applicant nor as a hiring manager. I've only had to use it once as hiring manager where the narrowed down by resume pool of candidates was still 70 people for only one position. I used the damn tool because I didn't see any other way to filter it down to a number I could conceivably interview live on zoom.
If one is down to 3-5 candidates, AI tools of any sort are inappropriate. As with all things AI, it's a tool and not an excuse to not do the job.
That's garbage. That's def an option someone selected, to not allow re-takes. Hopefully they just didn't understand the impact and course-correct if they use it again.
Knowing the workflow for mine was unlimited retakes made me feel a bit better, though I still didn't like the tool. So the person who chose to record from the phone with their camera shooting up their nose had every opportunity to rethink that choice. The person who opened and closed with a string of expletives chose to hit "submit'.
