Was contacted by an HR person from St. Luis who got my resume from a friend who works at the company. Scheduled an in person interview with the hiring manager, and a follow up interview with 2 other engineers. They asked a few technical questions based on what was on my resume, then asked me to whiteboard a recent network design i worked on. that led to questions about my design decisions and how specific technologies i implemented worked. i got an offer 24 hours later, but declined. the job seemed less interesting than what i was doing at the time. i would have been farmed out as a contractor on a specific contract for a while. the hiring manager was very unprofessional, and asked if i only interviewed to "get more money out of my current employer", he also bad mouthed several people i had worked with in the past we both knew during the interview process. I thanked him for the opportunity and hung up.
