Within a period of a few months in Canada I had several jobs in restaurants where I worked as a kitchen helper etc. These very short term jobs have nothing to do with my studies and the NOC I am applying under. For my personal history, do I need to list all these jobs with beginning and ending dates or can I just say "Miscellaneous jobs in restaurants" with dates say Jul 2015 - Dec 2016? I do not even remember the dates I worked at some of these jobs.
