Contrary to this, IRCC did advise me on my NOC. Along with my email, I have listed down the job descriptions which were stated in my certificate of employment, the course I have studied and my ECA result. They replied but stated that they cannot find an exact NOC and requested for the type of industry I work in and the minimum qualification required to be hired. After that, they advised the NOC but with the general disclaimer that the final decision for selecting the most appropriate NOC code is each individual's responsibility. However, the NOC that they have advised doesn't really tally with my job descriptions. In the end, i decided to follow the NOC which most likely resembles my JD. Crossing my fingers that I did the right thing..
