  • Requirements / Prerequisites

    • Foundational Power BI Understanding: Participants should ideally have a basic familiarity with the Power BI interface, an understanding of what Power BI is used for, and perhaps some initial hands-on experience with creating simple reports and dashboards.
    • Basic Data Concepts: A rudimentary understanding of data concepts such as tables, columns, rows, data types, and relationships will be beneficial, though key concepts pertinent to Power BI will be reviewed from an interview perspective.
    • Microsoft Windows Operating System: Power BI Desktop is primarily a Windows application; therefore, access to a Windows operating system (Windows 10 or later) is necessary for full participation.
    • Power BI Desktop Installation: Ensure you have the latest version of Power BI Desktop installed on your machine prior to the course commencement. It is a free download from the Microsoft website or Windows Store.
    • Commitment to Practice: A willingness to actively engage in practice exercises, mock interviews, and to apply feedback for continuous improvement is essential for maximizing course benefits.
