Anonymous Interview Candidate
I applied through an employee referral. I interviewed at L3Harris
The interview process was pretty easy. Calls with recruiter, hiring manager, and manager of the hiring manager. Overall, the interviews were good experiences and weren’t very challenging. What I didn’t like is that I told the recruiter how much the salary would have to be for me to switch jobs and the offer ended up being $5k under it. Otherwise, the process was good and quick but rating as negative because it was a waste of everyone’s time if they weren’t willing to meet the salary requirement.
