Bloom Energy Process Engineer interview questions

The first phone interview was with bloom energy recruiter, the recruiter did not call me at the scheduled time. After inquiring it was rescheduled. The interview went well. A day later I got a call to from some lady to schedule an appointment with the hiring manager. The hiring manager called in 15 mins late, sounded totally disinterested did not introduce himself and just asked me can you go through your resume. As I was going through my resume he asked me if I knew anything about six sigma tools told him yes. Then it seemed like he started walking or was on a speaker, but it was hard to hear a word he was saying that is when he asked me something I did not understand, I repeated the question to conform what he said....he totally got disinterested and said "well I am sure I will find people with more experience thank you for your time. Do you have any questions?" That was about it....10 mins tops.
