I applied through a recruiter. The process took 3 weeks. I interviewed at Protocol Networks (Cambridge, MA) in Feb 2020
Interview
I got to a final interview with the CEO (Adam Belesimo) and then was cowardly ghosted. If you don't want to hire someone, that's fine, nothing says that you must; but have a spine and let them know you are going in a different direction. Hard working network engineers would do well to avoid a company with a CEO that acts in such a way.
