This could be unrelated: I was interviewing with them recently, had a technical interview scheduled, and then out of the blue last week they emailed me and told me they were discontinuing the process as they had now filled all positions... this was not the result of an interview, a had already "passed" the previous one and scheduled the next.

I assumed it must have been something about me (and it still could be), but the timing of this is interesting.

I am also in Canada which is where the person was told the hiring situation had changed.
