Popeye: I write just to chime-in with - I hope - some words of support.
I garduated law school in top 10% of my class (3.8 GPA, 2nd tier but respected law school). I attended law school evenings. You do not get a break, same grading system - and same bar exam(s) apply. Work 9-2-5 and take notes 6-2-10, then read cases all weekend. I hold a PhD and BS w/ honors in my techical discipline. I had 15 years experience, including two expat assignments, in industry. It took me 6 months to get that "break" at a really good law firm. The economy was bad, but not as bad as it is today. My DOB ( I was 40+) didn't help. Dumb luck and coincidence played a big role in landing that first "break". You may be looking at 12+ months in this business climate. Lost that job in the recession. Now I'm 50+ and, w/ circa 15 yrs prosecution and opinion experience at at two really well-known firms, the best I can do is contract / project jobs and, ghads, an occasional doc review project (gotta eat!).
Concerning employment w/ the USPTO, the US government is the "worlds largest law firm". I've learned gobs on this site re: how the USPTO (dis)functions. I don't know how it makes hiring decisions. But you have earned a veterans preference. I have no idea how that is implemented.
Hang in there! To borrow a cliche'; the job search is a marathon, not a sprint. Or as a popular (w/ tourists) t-shirt here in NYC puts it "The Bronx - Only the Strong Survive"
Often a prospective employer, legal or otherwise, looks at three things: can do, will do, and "fit". Can do you have covered. Will do? How intellectually versatile are you? Or are you, as Germans say, a "Fachidiot" Examples please. Fit? Are you well-rounded? A team player? Good people skills? This has to come through in an interview.
All the best, NJP1
