    4. Develop your Portfolio

    Prepare a portfolio to showcase your previous projects and experiences about Tableau development. Prepare a repository of dashboards, visualizations, and analytical insights. Talk in-depth about the different Tableau functionalities and techniques you used for the creation of the product. The portfolio gives the interviewers an idea of the depth of your experience and creates a positive impression of your work.

    5. Go through common interview questions
