Hypotheses:

1. They don't know about RSS. Websites are often just something like WordPress, those who manage them don't actually "build" them.

2. They want to track the visitors. I think it's completely useless, but they want to know who clicks where and how many people open any particular job offer. There is no tracking with RSS.

3. Why would they care about the user experience? People should feel lucky to apply to their 15-interviews process.

Because if HR people knew how to do that, they wouldn’t work in HR.

Seems like you'd be one of among dozens who would actually do that.

I put that on our website, since I love RSS. We are not a tech company, though, so none of the potential applicants use it. I think some scraper/job boards consume it, but that's it. I built it mainly for fun and to signal virtue :)
