Informal meeting with Executive Assistant in her office. Met mid-day at the office and was walked back to interviewer's office, where we sat and discussed role. There were no strange/unexpected interview questions, and I was offered the job at the end of the interview. I was recommended to the role through a client of the company, so I already had a good sense of what the company did. I dressed in business casual attire (dress pants, blouse, etc.) and the woman interviewing me was dressed casually (jeans, sweater, boots).
