Countries to apply for a job abroad?

There are better choices for your professional plans. The problem with the countries you mention is that their population is minuscule, which means the number of job opportunities will actually be low. I'd give it a shot in one of the following, because you are simply going to be able to choose from a much larger number of possible positions:

US

UK

China (nice! Really! I spent three years there and loved it, and the money is OK)

Hong Kong (superb place to be based as an engineer)

Singapore (now that one could be indeed easy, because they are hoping to increase their population)

The ones you had mentioned are pure lifestyle choices. Canada, New Zealand... I have lived in those myself, and have to say the idyllic image is not a realistic reflection on what your life might be like, because the pressures of keeping whatever job you may find are tremendous, and opportunity scarce. With enough money, life is good anywhere, and with enough job opportunities, there will be enough money.

MBA is a glut on most job markets, and NOT a qualification for any employment visa anywhere. Not Canada, Norway (you have to be fluent in Norwegian anyway), NZ, US, or anywhere else.

If you hold a bachelor's in electronics engineering, even if you were actually working in that field, you do not qualify. You'd need a minimum of a master's degree in engineering, plus sufficient experience to have developed specialized expertise. However, US has laid off over 100,000 engineers in the past year. Canada, Australia, etc, have also had mass layoffs of engineers (20+% of Australian engineers have lost their jobs in the past year). There are no jobs for you even if you qualified.

Canada is NOT an easy place to move to. If you have a unique skill that is in demand it might be possible, but, it certainly is not easy.
