I had my first two rounds today and it didn't go well as expected. I got nervous in the first round and took more time for the first question. Second question, I was able to identify the optimised approach but couldn't finish the code in time.
Second round went well, was able to give the optimized the solution and completed the code. However, due to scarcity of time second code was not reviewed in my presence.

I have two other rounds too in the upcoming week, will write an interview experience after that.

I need your opinion here, that if Amazon doesn't find a candidate suitable after first two rounds, why they schedule other rounds? After today's rounds, I don't feel confident and if I have been already rejected why I have been asked to appear for other two.
