It's bad for any level, not just senior. I literally haven't received an offer in over a year of varying interviewing, because no matter what I'm applying to, I get hit with a hackerrank test that compares me to probably anyone in terms of simply whether or not I solved every test case. Others will put me through 5 interviews before deciding to not hire. I can't support myself financially with programming skill as a result (in Canada). It was bad 5 years ago, it's worse now.
