I have been applying to positions throughout the summer. I had a few interviews in the spring, a few in early June, but have not heard anything back since then despite applying to anywhere from 4-12 jobs a week. I have heard hiring tends to be done in rounds. Is July usually a slow time for hiring? Do calls typically start up again later? Any information from someone who has been in the field longer would be appreciated -- I'm starting to get fearful about my employment.
