I'm sure this happened somewhere at some point in time, but IMO it's becoming a myth blown out of proportion.
I've never actually worked at a tech company that had any sort of automatic resume filtering software. As a hiring manager, we didn't even have HR pre-screening resumes for us. If we did have recruiters, they were competent and incentivized to find good candidates (e.g. wouldn't be unnecessarily rejecting good candidates because they were missing exact spellings of keywords)
It would seem ludicrous in 2022 and this hiring crunch for a tech company (one that you'd actually want to work for) to arbitrarily filter out resumes based on incomplete keyword searching.
