So the title of your thread implies racial profiling exists but in your post other than saying you completed a telephone interview but after the face to face you did not succeed, no other comments on the thread title how this conclusion reached and specifically Saskatchewan.
Plenty of people interview well on the telephone but when comes to the face to face they do not come across quite as confident for whatever reason so they do not get the job over someone else.
Nobody ever says immigration is easy and too many people , not implying yourself, think that they can just move from a country where they previously had a secure well paid job and just slot into the same life on arrival. It will take time with a lot of disappointments and too easy to speculate the reasons for the latter as opposed to just moving on to the next application. Just have to believe you will succeed, it will be worth it and ultimately if Saskatchewan is not for you try another province given once a PR the country is yours to live and work wherever you want.
