Applied Engineering Inc. Design Engineer interview questions

Initial 30 min phone interview with a recruiter, followed by a 90 min interview with the hiring manager and a director. From application, to the second interview took about 2 weeks, but then was about 2 months until an offer was extended. I gave them my salary expectations after the recruiter call, but in the final offer, I was given an incredibly low wage that they were almost entirely unwilling to negotiate. Benefits also seemed well below average for the area.
