Hello,
I am an Automotive Mechanic and I look arround on the Jobbank website and I write the Companies, who I am what my skills and they make a Skype Interview with me.
I make it very easy I write always a small application for the jobs not a big letter.
This is my experience what I can told.
One other what I want to say here in the Forum I ask the CIC over email how long are Certified copies valid. The answer :
THERE IS NO EXPIRY ON CERTIFIED COPIES. I asked because I don't know and I say here maybee someone is Interested about that.
