Frequently asked questions
Can I prepare for a Power BI interview in 7 days?
Seven days is enough to revise and sharpen, not to learn from zero. Use the plan to cover each core topic once, practise questions daily and finish with a mock interview.
How do I add questions to the plan?
On any question page choose Save to → 7-Day Job Prep. Saved questions show up at the top of this page.
How many hours a day should I study?
Two to four focused hours a day works for most people: one hour of revision, one to two hours of questions, and the rest on projects or mock answers.
