I have Amazon interview scheduled next week and have these 3 questions in mind. Would be more than happy if you take out few minutes and answer them.

1. Should LP stories always related to professional life example? Or we can also put personal experience related to questions like - Most difficult situation. I have professional exp of 11 months.
2. My interview will be online. During coming up with solution, Is it okay to use physical notebook to come up with solution? Because I feel that Interviewer will not able to see what's going on in notebook so he might feel detached.
3. After hearing qus from interviewer there can be instance where I won't have idea where to go for few seconds which will lead me to silence for few seconds. Is that okay?

Thanks in advance :)
