They are seeking Marketing Mix Modelling Consultants at Analyst, Consultant, and Senior Consultant levels.

• Senior Analyst (2 years’ experience) – up to £45,000
• Consultant (3-4 years’ experience) – up to £55,000

Interview Process

• Stage 1: 30-minute conversation with the Hiring Manager (experience, CV review, role overview).
• Stage 2: Dataset exercise and presentation (focus on both analysis and presentation style; the dataset includes subtle “easter eggs” to test attention to detail).
