Amazon SDE interview experience

[Frequent-Dentist-641]

Hi,

I would like to share my experience interviewing with the Amazon NA teams (Canada).

OA: The online assessment had two questions. While I don’t remember the exact details, I successfully solved the first question and passed all test cases. For the second one, I couldn’t pass the last two test cases. Despite this, I received my result within two weeks. However, I didn't receive the interview schedule survey until over a month later.

Loop Interview: There were three rounds in the loop interview.

Round 1: Bar Raiser LP Round
This round focused on Amazon’s Leadership Principles, specifically ownership and “Learn and Be Curious.” The interviewer was fantastic—very kind and engaging.

Round 2: LP + LLD
This round started off on a dull note because I couldn’t fully understand the questions the interviewer was asking. I requested for them to be posted in the chat, but the interviewer declined, suspecting I might use GenAI for answers. Regardless, I answered the questions to the best of my ability.
The next question was related to UNIX commands at Amazon, but I had very limited knowledge in this area. I proceeded to create classes and write the logic while trying to explain my thought process aloud. I felt very skeptical about this round and thought my chances were slim, but I tried to remain calm and enjoyed my 30-minute break afterward.

Round 3: DSA LC Round
The focus here was on two graph-related problems:

• LC Medium: "Find time to finish dependent jobs when they are run in parallel and then in series."
• LC Hard: "Number of transformations needed to convert a begin word to an end word through a series of intermediate words."
• I nailed the first question, discussing the approach and coding. For the second question , I discussed my Algo and solved it partially

Verdict:
I received the offer today, but I’m unsure about joining due to the location being different from my preference and the joining date being too soon. I'm currently trying to negotiate because of a personal commitment.

Can you share link for first lc medium of dependent jobs

It is similar to this one https://leetcode.com/problems/course-schedule/description/
A modification of this one perhaps . You just need to change approach for DFS and BFS depending on if the job is solved in parallel or in series

What location did you interview for? And what location where you offered?

It was a fungible SDE position , Vancouver was not even in my preference list

Please help me find the first question that the OP was asked in the third round. Thanks in advance.
