How to use this list

  1. Treat it as a map of the market, not a checklist. Tailor to the posting you are applying to.
  2. For each skill you really have, make sure it is written on your resume, in the posting's wording, where you used it.
  3. Leave out skills you do not have. Listing them can cost you in the interview.
