The interview process was similar to most of the others posted in the review section. It started off with a 30-minute phone call to answer basic questions, progressed to a phone interview with the hiring manager and then an in-person panel interview.
The panel interview lasted two hours -- one panel per hour with five people in each panel. The questions were a mixture of STAR and industry/role specific ones. Expect to be able to answer questions on the types of data you've processed and cleaned, software familiarity levels, brand strategy and research methodologies. Solid knowledge of Altria products can also be beneficial.
For me, I realized that they wanted someone with deep proficiency in data hygiene and analysis (SPSS and r knowledge came up several times in the interview) and that's not really my cup of tea.
