First Solar Financial Systems Analyst interview questions

I applied through the First Solar website, and was contacted by an internal recruiter. She was very good and thorough, spending an hour and a half asking me questions and getting to know me. She then progressed my application to the hiring manager, who spent an hour with me on another phone interview. Days later, I was invited back for the panel interview. The panel interview was about seven hours, counting a hosted lunch with the team. Up to the lunch, everything went well. And then, the final interview with two finance managers (both of them women) took a very odd turn. The interrogator on the left was wide awake and asked all the questions, and the scribe on the right would type furiously in her laptop and look bored. At one point, the scribe passing out, and this happened three or four times over the course of an hour and a half. The interrogator ignored her narcoleptic peer, who would rouse from sleep and start typing furiously, and glare at me. I don't know if this was supposed to be a stress interview tactic, but it certainly seemed odd at best, and quite unprofessional. I heard nothing for weeks, and then checked the website. The hiring manager chose to change the requirements from "Must be willing to train to be the administrator of SAP BPC" to "Must be have SAP BPC experience". I had made it clear from the very beginning, when I interviewed with the recruiter, that I had SAP FI, CO & SRM experience but *no* BPC. This seemed like a real waste of their time and mine. I called the recruiter, who confirmed that the requirements had been changed. She apologized on behalf of the company. The recruiter realized something really weird had happened - and I didn't even tell her about the narcoleptic finance manager. The End.
