I applied online, the process took around one week. First a simple online exam of basic math/ statistics ( 10 questions), then a interview with HR ( simple questions of your CV and pasy experiences and also they explain the job, and how they work) and then days later they call for a case study presentation in front of a panel (they give you a crosstab of data and asked to draw some conclusions and make a recommendation)

Initial Phone Screening with HR is pretty standard, not much technical questions. They do test your aptitude for marketing analytics via conceptual questions. If you clear the screening, there is a written test that is given to you. This is mostly quantitative questions with an essay in the end. 2nd round was with 5 professionals within the Custom Analytics department. The interviewers ranged from Snr Analysts to VPs. The questions revolved around general marketing concepts and some statistical techniques, especially linear regression.
