Chelton Graduate Engineer interview questions

Conversation with couple of engineers and to-be managers. Questions about design of PCBs taking into consideration component availability and procurement complications. General questions about omni antennas. They took me around the plant showing me stuff they had been working on. Asked me how I would design certain things. After this, I receive an offer which I gladly accepted. The offer was rescinded couple of days later when the team realised the security requirements of the application. No compensation was offered for time nor transport.
