Business Network Consulting - BNC interview questions

First a technical screening. Then another technical screening. Then a test on a whiteboard with a SR. Engineer, and in the end, its all for a low paying position being a field support tech who doesnt make that much.

Was contacted by a recruiter over LinkedIn and asked if I had time for a quick chat with HR. I told HR my salary before the talk started. An hour later the call ends and they proceed to offer me 15,000 less than I currently make. After I explained to them what they where offering was less than a tier 1 makes they sent me an offer for a second interview a few weeks later where they refused to tell me the salary.
