Practicing technical questions on your own is helpful to study for interviews, however it does not compare to solving a challenge given to you on the spot with someone watching. It really helped me to practice talking out my solution to the interviewer.

Thanks. The exercise was interesting and it was good to know what you thought about my performance. The part I was most looking at are the feedbacks from the expert. The live feedback was already useful to know where I have to improve and how. I think that in the end I would have prefer to spend 5 minutes less on the implementation to have a full 10 to 15 minutes for the feedbacks.
