Applied online. Received an email from hiring manager in 2 days. Set up telephonic interview the next day. I received email the same day asking my availability for onsite interview. Went onsite and was interviewed by 4 ppl (including lunch interview). Hotel and travel arrangements were good. All the people I met were very friendly. Lunch interview was mostly non-technical and looked like behavioral testing. Basics of communication system - Mainly concentrated on receiver section (synchronization, equalizer). OFDM, CP, Fading, HP filter, C code for FIR filter and other questions based on projects in resume. My interview went very well. Unexpected was a reject email after 2 weeks.
