3 match your NOC
3 match another NOC
Rest 2 are from 2 different NOCs
You can choose from first two NOCs in this case even though less than 50% duties match.
This makes it a weak case.
If you had 5 out 8 duties matching with NOC, it’d be great.
In your case, 3 out of 3 duties are matching, 100%. Should not be a problem.
If the experience certificate looks small, ask the boss to throw in a random duty, albeit close to your actual duties. That’ll still be a 75% match.
All this is my opinion BTW, I’m not an expert, nor have I been through this. Wait for other opinions before acting.
