From their website, the poster also has a recent PhD (2019), so I'm a little surprised that the talk request caught them so flat-footed. I gave job talks at ~85% of my interviews after grad school, and those talks were usually adapted from my PhD defense. I did make some changes: add in more background, emphasize parts of the project that are more similar to the job, etc. However, this certainly wasn't weeks of work; more like 1-2 evenings to edit the slides, plus a few run-thrus to practice.
