AAR interview questions

I am working as a contractor through MST. I have a 6 month contract. MST set up a phone interview and AAR was supposed to call me. They called 1 hour late and blamed it on losing the phone number. The interview was short and (base on what I've seen this first week) not very representative of what is actually going on here. It was odd to get an offer the following week without an onsite interview. I accepted b/c my husband is involved in a start up so I'm geographically constrained and wanted something with a finite timeline.
