Computer skills and technical skills are indispensable in this contemporary era, and any significant experience you have with software relevant to the position in question will be highly desired. Be sure to tell your interviewer if you do have such skills, and highlight your expertise if possible. In addition, typically any good experience using the two main operating systems, OSX and Windows, as well as general office productivity programs like Microsoft Office, Apple’s iWork suite, and even Google Drive will most likely be useful in any position.
