Half-hour phone interview scheduled by recruiter through email. Was told I would get a call from a hiring manager but never received one. Emailed and called the same recruiter to notify her, and she got back to me within the hour and apologized, saying the hiring manager was unavailable at that time. Rescheduled the phone interview for a later date. Went very well, simple behavioral questions and asked about projects listed on my resume. A few days later, I received a phone call from another recruiting manager to set up on-site interview for the following week. I flew in and out of San Diego on the same day. My interview was an hour long with 6 panel members. Few behavioral questions, but more technical questions that tried to gauge my level of fundamental engineering background and also attempted to see how I would handle pressure. I guess I tanked the interview because I received a generic rejection email the very next day.
