Actually getting a nonacademic job

I (finally) finished my PhD in July and have been hunting for a non academic job since then (pref. industry).

I've applied to numerous jobs, and I'm not even getting any interviews. Sadly, my network is basically non-existent and so of no help.

I'm in the US not not very location limited (NE) and have been looking for jobs involving microbiology, immunology, or molecular biology. I honestly wouldn't mind a non-research job like support with assays or sales but again, I have had no luck.

I've only been applying to jobs that I seem qualified for and with not too many applicants. Those of you who have recently managed to get out of academia and into industry, what did you do? Any tips?
