You go in the office and they try to figure out or remember who you are. Then they look for your application. Finally you get to sit down in a shared office where people walk in and out as they want during your interview. The manager was distracted a few times, others come in and ask him questions, he would suddenly carry a conversation with whoever comes into the room and says "sorry" and continue with the interview. Oh and answering his calls, I thought interview etiquette is the phone stays off.
