Started with a call from HR for a couple of brief questions then passed to a manager a week later for another phone interview. About 2 weeks later a call from another senior manager for a 20 minute conversation via phone. Finally scheduled for an in person interview a week later. Arrived and did the formal written application waited for an hour to get called in, 20 minutes with first guy. Then lunch with a couple of employees, very nice guys 9 and 13 year employees. After lunch I waited about an hour for interview #2 that took about 20 minutes, then HR interview for 1/2 hour and then meeting with senior manager and a quick tour. Elapsed time 6 hours. I thought the interviews went well and they asked some very good questions. The overall atmosphere seemed a bit sterile and lifeless given that they are an AV related company, no BGM no video playing, no technology demonstrated in public areas. Just seemed a bit strange. Everyone was super nice, looked perhaps a bit overworked but arent we all. No offer yet but I am eagerly waiting.
