Interview was with 10 people at once. Many simple questions. Then interview moved to a informal presentations on the fly. From block diagrams, wiring diagrams, asts. All was fine, but a 10 on one format should have been a refined and prepared presentation. Had I known I would have made one. All an all enjoyable interview, but after multiple attempts of reaching out after the interview no feedback whatsoever. Not even a decline or thank you, unprofessional.
