You don’t need to memorize 50 questions. You need to prepare with purpose.
Here’s a simple prep framework we use at WebVeda:

• What does this company value?

• What are 3 problems I can help solve?

• How does this role align with my long-term goals?
  And 7 more in our downloadable prep sheet. The idea is simple: be self-aware, do your research, and practice your delivery.
