From my experience
What are the specific tasks software quality assurance engineer and software tester does? Assurance engineer has more wider responsibilities compared to software tester, like to ensure the recommended code coverage statistics, Release notes and other documents validations, Testing etc.
Does companies hire non resident employees even though they have not mentioned it in the advertisement? Yes and No Yes - when you already have a work permit/privilege to work in that country. Companies will even pay the relocation expenses unless it is stated. No - if you don't have a permit to work in that country or the employer is not willing to go down that road. You will have to double check that while applying
