I know that the typical answer to "should I include hobbies/other activities on my resume" is no. However, I've also heard that many companies like to have medically trained employees, and in some non-medical fields, including CPR certification on your resume is common if not expected.
In my field (software engineering), however, the certification is at best tangentially related to my job, depending on the type of software my company writes.
Should I include my EMT certification on my resume?
