First Solar Development Engineer interview questions

First 30 minutes phone interview with a recruiter then full day on site interview. About 5, one hour interviews with engineers, hiring manager, senior scientists. Most of them are nice. Group lunch with other engineers. 15 minutes presentation. Hiring Manager looked not interested in interviewing me. He was yawning during the interview. Looked liked he already has made a decision. It was a waste of time.

Received email for a phone interview. The whole phone interview is talking about the job related knowledge and some personal routine questions. The whole phone interview is about 30 min and questions were asked is not hard to answer if you are in the industry.
