@GeriC hello po. It’s really challenging pag ang line of work mo medyo hindi relevant sa tinapos. I did not submit a referral letter, ung typical COE lang ang meron ako. But I prepared a Statutory Declaration signed by my Superior if ever na hingin. I believe same lang sya sa referral letter, baka how you presented lang. Baka po mas ok gumawa ng bagong referral letter.
Sa CE writing, Suggestion ko po to focus on technicals ng pagiging IE. Kung ano po mga processes, theorical concept/formulas and standards na pwedeng maapply. I treated each CE as a thesis. May problem, may solution na ako mismo ang nakadiscover or nag suggest, as well as results- positive feedback from client, etc. To make sure na tama ung mga nilagay ko sa CE, i had it reviewed by a colleague na practicing Engineering talaga. Also referred sa mga standards.
