does on-campus job counts in past 5 yr employment history in ds160?

Hi,

During my MS, I worked on campus in university and filed tax returns as well. My job was in graduate school cafe as server/cashier etc. no specific title.This job falls under past 5 years employment. Do i need to enter this info in my DS 160?

if yes, then i didnt even have a real job title and dont even remember joining date/leaving date. please help. thanks!
