Campbell Scientific interview questions

I had 2 interviews at Campbell Scientific for the Account Manager position. The requirements I discussed with the HR manager, where different than the ones of the direct manager. After the 2nd interview, they stopped all communication, and the HR manager did not answer my e-mails. Although I told them that I had already received another offer and I needed to get their feedback as soon as possible. I ended up taking the other offer.

Phone screening interview followed by a group/panel interview evaluating for General fit which, if successful, is followed by a 2 days paid technical interview I which you have to complete exercise with Campbell equipment.
