I applied online and was contacted to schedule a phone interview 2 weeks later. I waited patiently in a quiet environment for my phone call on the scheduled time and day but I ended up waiting for longer than an hour. When I realized that they wouldn't call, I emailed the HR contact asking to reschedule. She apologized and said they would reschedule for later in the week. The next day, she told me that they would fly me out to the office in Massachusetts for an onsite interview. I agreed, traveled to the office the following week, and had an interview. I felt that the interview itself went well and I don't usually think that about most of my interviews. I waited for 2 months and I never heard back. I didn't bother to call for a follow up because I had accepted another offer from a different defense contractor.
