I have been working at US Patent and Trademark Office full-time (More than 5 years)
Flexible work schedule, supportive management
Sometimes unpaid overtime is needed to meet production requirements
I applied online. The process took 4+ weeks. I interviewed at US Patent and Trademark Office.
Applied online, after about 2 weeks, I got an email for an online/phone interview. They asked typical behavioral questions. It's was a very simple process, but it seems like the interview did not matter if you were selected or not in the end.
