Getting ready for Cross-Device Identity Interview Questions will help you connect fragmented user journeys across screens and devices. Start your preparation with these Attribution & Marketing-Mix Modelling interview questions to see how identity resolution fits into your overall mix analysis. Then deepen your understanding by tackling the marketing elasticities practice MCQs and learn how demand shifts affect channel weight. Next, hone your scenario skills with the budget optimization simulations interview guide for hands-on forecasting practice. Finally, wrap up your study by exploring the multi-touch MMM hybrid interview resources to master integrating cross-device signals in hybrid mix models.
