Had an intial phone interview for half an hour with technical hiring manager and two other people. Got an email after a month with an invitation for a face-face interview. Schedule was sent along with the email. Got to site at 8:30. Was told details about the job and expected duties from 8:30-9:00. Met 4 technical staff in one-one half an hour slots. Friendly information exchange about my past experience and skills, and what they do. One hour technical presentation from 11-12. Lunch for 1 hour. Again 1-1 interviews with individual staff for 2 hours. Interview over around 3:30

Standard interview. Generic HR questions. I was followed up with another phone interview with the manager. No specific question except just asking what you do, why are you interested in the company. In the end, they canceled the position.
