I reached out to an Amazon recruiter after seeing a post about an SDE-1 opening for 1+ years of experience and received the test link within an hour.

Online Assesment :-

It included two coding questions—one Leetcode Medium and one Leetcode Hard (I don't recall the exact questions as I took the test at the end of January). There was also a Work Simulation assessment.
I have solved both the questions with all testcases passed.

After about 15 days, I received an email for the technical phone screen round, asking for my available date and time.

Technical Phone Screen (1 hour):-

The Interviewer was cool. We started with introductions and then moved to coding questions.

1. https://leetcode.com/problems/path-sum/description/
2. https://leetcode.com/problems/path-sum-ii/

Solved both the questions. Expected to explain the time complexity and space complexity for both.

After two days, I received a call informing me that I had cleared the technical phone screen round and was asked for my available dates and times for the Loop Interviews. She explained that it would consist of three rounds, each lasting one hour.

Loop Interviews Round 1 (1 hour):-

The interviewer was a Senior SDE. We started with introductions, followed by two Leadership Principles (LP) based behavioral questions. He asked follow-up questions on my responses and seemed satisfied. Then we moved to the coding questions.

1. https://leetcode.com/problems/intersection-of-two-linked-lists/description/ (Solved)

2. This was a hard question.

   A binary search tree was created by traversing through an array from left to right and inserting each element. Given a binary search tree with distinct elements, print all possible arrays that could have led to this tree.

   I was stuck here and I couldn't come with an approach. So we moved on to the next question.

3. Design Stack Implentation with push, pop and min (return minimum element from the stack) operation with O(1) time complexity. (Solved)

Loop Interviews Round 2 (1 hour):-

He was the same interviewer who took my phone screen round. So we directly started with coding questions.

1. https://leetcode.com/problems/word-break/description/ (Solved)

2. https://leetcode.com/problems/longest-substring-without-repeating-characters/description/ (Solved)

   He then asked two Leadership Principles (LP) based behavioral questions.

Loop Interviews Round 3:-

This round with the SDM was initially scheduled before Round 2 of Loop Interview but was postponed due to the interviewer's unavailability. I received an email about the rescheduling and am currently waiting for the new date.

I will update the post after further progress.
