One of my friend who went as a immigrant in 2007, he told that chances of getting interview calls depends on How well your Resume is written.Also you should have certifcations OCP,PMP etc.
One thing is for sure that we have to try for developer jobs first and then look for better options.
If we are expecting Manager jobs from the begining, it would be tough .
Concept of manager in Canada is a person with 15+ years of experience.
I have worked in canada in 2006,i have seen that getting a jobs as developer /Sr. developer is easy.
Also what matters is you skill set, if you are Oracle ,Java developer ..then their are many people available in local market.
If you have niche skills chances are better.
If you have Experience in BIG US MNC, that would also help.
I have seen people with 20 years of exp. working as Sr. developers.
Personally i am ready for developer /Sr. Developer postion to start with.
I am a PMP with 13 years of IT experience and 5 years of project management experience.
