Inkerman Intelligence Analyst interview questions

Short notice interview request, odd question on career gap 15 years hence, and a one-page brief on Middle East prior to interview. Was told I would hear back from them shortly. Heard nothing. I called and emailed, and was ignored. Given the time invested to develop a one-page analysis on the Arab Spring, and the interview, the inability to just say 'thanks for your time but it's a no', and just ignore me, is lack of basic courtesy.
