First Solar Project Development Engineer interview questions

First phone call was with recruiter/HR for screening interview. Second interview was an on-site interview from 8 am to 12pm. 30 minutes per interviewer/panel. Never heard back after the on-site interview despite follow-up emails sent. Considering this opportunity closed. For future interviewees I would suggest asking for a phone interview with the hiring manager prior to the onsite interview. The job description was not clear that the role was not a design role and was in fact a front-end site identification/evaluation role, which I honestly preferred but it was probably clear to the hiring manager that I didn't realize that prior to going in.
