Vulcan Spring & Mfg interview questions

I was introduced by a recruiter. I sat down with the head of HR and another person who did not speak. I assumed she was the sales manager at first but afterward learned she was another HR consult. The conversation flowed with typical questions. When done she asked if I had time to meet some of the team. After returning to the conference room she said they were not available. She then said a 2nd interview would be set up normally. I received an email with some questions, discussed in detail. She said they would most likely call me by the end of the day. When this did not happen I sent a follow-up email several days later. No response. Then again. No response. I finally sent a final email thanking them and asked for any feedback whatsoever. No response. I can appreciate them changing their minds but after the efforts put out and then being ignored was quite disappointing.
