Multiple NOC codes experience with gaps in between

My NOC codes are different with few months break, so I’m not sure which NOC code I need to use when filling my express entry profile for better score. As I read On Canada.Ca website for express entry eligibility, it mentions the job related NOC code has to be Continuous and full-time. Can someone please suggest? Also does the title of our roles on paper should be exactly listed under the NOC list ?
