That goes down with volume. If you apply to a large number of jobs then you won't worry about those who didn't call you back because you'll be too busy scheduling and attending interviews. Of course, if you apply to a large number of jobs and don't get any callbacks then that's a strong signal that you either need to update your resume, update your credentials, or seek employment in another field.
