What tense should I speak in when writing about myself on a resume?

I’m putting together a resume, and I’m wondering, when you explain in detail about certain aspects of the resume (jobs, awards, etc.), what tense do you speak in? Do you say, “I won this award for doing ‘x’”, or do you phrase it in a different tense, like “Award received for going ‘x’.” Should it be done in first person or third? (Let me know if you’re confused, this is a confusing topic.)
