It takes time. Keep practicing by - re-reading, doing hands-on exercises. There are many fabulous resources shared by our fellow HNers. I think you got what you asked for!

Couple points from me:

Have someone conduct your mock interview, once you think you are ready. Also, don't hesitate from appearing in an interview at a company which you don't plan to join. Another good way to practice and demonstrate your skills.
