Situation with job experience letter

[imijoon]

Hi everyone.

I worked for a company in my country (outside Canada) for about 5 years. During these time I started as an Electrical and electronics quality control technologist (NOC numeric code: 2241, skill level B) and after about 3.5 years I got promoted to Electrical and electronics quality control expert with the previous duties plus some supervisory duties and worked about 1.5 years in this title. My problem is that I can't find the proper NOC aligned with the second title.
I was thinking, as my first title is a NOC B, and its duration is enough to get the maximum point of a foreign job (3.5 years), and because I can't find a proper NOC for the second title, do as following:

• From xxxx to yyyy Electrical and electronics quality control technologist (NOC numeric code: 2241, skill level B):
  • Here are my actual responsibilities which are 80% aligned with the NOC 2241
• From yyyy he got promoted to Electrical and electronics quality control expert with more supervisory duties and his responsibilities are as follows:
  • Here are my actual responsibilities which are almost the same as the 1st title plus some supervisory duties which are not aligned with any NOC.

Again, as my first title is a NOC B, and its duration is enough to get the maximum point of a foreign job (3.5 years), should I be worried if the officer reject my application because of this letter?

Please help me with this situation.
