I'm not defending PA's job listing, because I do agree that it's absurd, but it's also important to remember that job listings tend to be for "ideal" candidates. Actual hired candidates are often far less qualified than the ideal candidate listed in the job requirement. For instance, ideally, I'd love to hire a dev that has 5+ years of professional PHP experience building web apps and has experience with machine learning systems specifically relating to fraud. But in all likelihood I'll be lucky to hire someone with 3+ years of professional PHP experience with zero experience doing machine learning. The hired candidate will likely be simply interested in machine learning. The hired candidate will likely have no experience with fraud-related topics. I can train you. I can teach you those things. But ideally, I wouldn't have to. Likewise with PA's job listing, ideally, they want someone who can do all of those things. Practically, they'll hire someone who can do a very small subset of those things. That said, it's a bit unrealistic to expect one person to do the job of four people (which is what this listing wants), especially for low salary, so... yeah, it's a bit ridiculous.
