Round I: Online Assesment
There were 4 sections in this round:

1. Debugging Section: It consisted of 7 questions to be completed in 20 minutes. Most of them were easy. Could be solved without difficulty.
2. Coding Section: It consisted of two problems to be solved in 70 minutes.

• https://leetcode.com/discuss/interview-question/699973/goldman-sachs-oa-turnstile

3. Behavioural Section: It consisted of about 25-30 questions. This section was not timed. For this I will suggest to go through the Amazon Leadership Principles.
4. Aptitude Section: It consisted of 24 problems to be completed in 35 minutes. Can be solved easily if you have practice of solving aptitude problems.

Round II: Technical Interview
The Interviewer was quite friendly and asked me to introduce myself and give an overview of my project. He then asked me 2 DSA questions.

1. Given two number in the form of sting, we have to perform two operations: Remove all the zeroes from the number and then add the two numbers.
2. Given two numbers in the form of LinkedList we have to add the numbers. But there was a condition that we cannot reverse the linkedlist.

Finally I would suggest anyone who is appearing for the Amazon technical interview to focus on proper naming of variables and code readability and reusabality aspects as well.

Good Luck !! :)
