Express entry Noc code

Hi,I have one question. I worked at restaurant for 4 months (manager position NOC B) and 20 months (office administrator NOC B). Can i consider it as 2 year experience… but i agree that both NOC are in B But code will be different such as for office admin will be 1121 or restaurant manager something eg 1124… will that be a problem… or i can go for it…job responsibilities also will be different… Could you please advice something

Yes, you can. I did it for my brother who had 1 year in Accounting and 2 years 2 months in stock trading. So he got full points for 3 years experience.
