The interview process consisted of three stages. The first was a phone screen with one of the firm's recruiters. This was followed by a coding exercise and then a subsequent one-hour video interview with two data analysts to discuss the exercise. The final round was a panel interview with four senior executive team members, which was quite an open-ended and detailed discussion about my prior experience, training and skills. They also talked about the various opportunities at Mathematica, both within my role and more broadly.
