There are only 2 rounds of interviews. The interviews will take place over Skype call if you're not based in Tucson, Arizona U.S.A. It would be difficult to reschedule, and hence more or lest stuck with the time slot given, which on both occasions, were in the evening (GMT time in my scenario) The first round is with the Business Development Manager. Interviews, are short, curt and carried out quickly. Definitely turn your 'Sales Face' on (i.e Excited, without pauses and signs of unpreparedness) Rehearse the above questions to be able to answer in short, concise, albeit interesting snippets. The second and final round is with the Chief Financial Officer, also over Skype, again in the same style as noted above.
