Hi. Could someone point me to communties where people gather, ask, and post resources for improving one’s resumé/CV? And if possible, communities that post work/job opportunities especially remote ones? Bioinformatics, Linked and Open data, Part-time operations associate jobs

Could someone point me to communities of the following if they exist: - Reuse, Upcycling and/or Repurposing - Knowledge graphs and/or Semantic Web - Steganography Thanks in advance :)
