Amazon SDE intern interview questions

The interviewer is helpful, and you have to listen carefully to what he is saying. Speak out loud through out the interview and be responsive to what he says. He asked me a question on linked list.

I had 2 technical rounds. In the first one, after the initial introduction, he asked me to write a program to find words (given in an array) from a grid which consisted of letters. The arrangement could be of any form, as long as the letters are adjacent. This took around 20-25 mins, with him dropping hints throughout, leading me towards an optimal solution. After around 3 hours, I had my second round. It was for around an hour, with them asking two coding questions.
