I was contacted by the recruiter after two weeks and had a phone screen. She contacted me again over that weekend (Sunday) to come down the following Tuesday. I was offered to be flown but offered to drive as I live three hours away and expense it. I met with two VPs who were very nice but basically asked the same two STAR questions over and over with slight variation. I received the form rejection email a week later. My issue with AMEX is that before (and after) I traveled I asked for their preferred expense report format without a response. While onsite, I asked the HR person regarding it as well and was told I would get it from the recruiter. After the rejection, I resorted to sending the recruiter a terse email regarding the expenses. She finally replied that they do not have a policy to reimburse non-employees. Ridiculous! A multi-billion dollar company does this to canidates? You should have told me this before traveling and I would have let you fly me down at your expense. She ignored all further attempts to discuss and I'm now out $275 in mileage and tolls.

HR interview followed by three rounds of functional, few rounds of telephonic and some face to face One to One interviews with senior people. Go deep into achievements and challenges oversome in your previous jobs or entrepreneurial ventures. Clear though process and being highly articulate is very important.
