Very professional. 1. Had a HR interview on the phone. Then a round a technical phone interviews with 4 H/W engineers. 2. Onsite interview with 4 other H/W engineers. 3. Lunch interview with H/W hiring manager. They paid for flight, hotel and meals. The people are very friendly and down to earth. I got the offer but could not accept because of location preference. Looked like a very good place to work and grow.
