I applied online. The process took 4 weeks. I interviewed at DHPC Technologies (Wharton, NJ) in Jun 2020
Interview
The process was simple and easy. 1 HR interview, followed by a meeting with the customer's group. It was overall an easy interview. DHPC is now Peraton Labs, so their interview process may be different now.
