Not HN-like, no, because it’s important for me to be able to filter out jobs based on various criteria, and HN has no filtering — which is fine for what it is, it just sucks for a jobs site.

In what sense? This need some more detail.

People post job ads and people comment on whether the job is desirable or appealing? People decide whether the companies are interesting to work for?

Huhhh... can you repeat the question?

There seem to be some extra words in it that shouldn't be there, and some other words are missing...
