They're pretty rampant in Canada. You usually get one of these types:

- Long home coding challenge (for no pay of course) - Hours of whiteboard coding talk. If you're lucky it relates to the job at hand, most of the time it doesn't - Doing coding tests online, either through their propitiatory app or through sites like HackerRank. - A conversation type interview, where you talk about the job (have only had this one in my recent attempt. Didn't get past that phase)

Of the roughly 30 interviews that I've done in the last ten weeks, only one place ever asked about my github profile (which I don't have yet, currently revamping it since most of the code was years old and pretty meh). Almost every one of them had questions about my linkedin profile though.
