Summary

I participated in a 1-hour technical assessment for Amazon SDE-I after completing the OA. I managed to complete one coding question and answered a leadership principle question, but struggled with the second coding problem which involved 2D DP on a DAG.

Full Experience

Time limit was 1 hour, I had to explain from brute to optimal, and this was the first technical assessment after OA:

The first question was simple but it took more time as I have to dry run an example and before coding I had already dry runned the input. Now, for second question it was 2D dp on dag, I was unsure and not confident as I had spend 45 minutes on first. And was not able to think about it, after few minutes I was asked leadership principle and what I did in a given condition. So, did only one coding question done, and one leadership principle.

I am goona cry now.

Interview Questions (2)

Q1
2D Dynamic Programming on DAG
Data Structures & Algorithms

The second technical question involved a problem that required solving using 2D Dynamic Programming on a Directed Acyclic Graph (DAG).

Q2
Amazon Leadership Principle Question
Behavioral

I was asked a question related to an Amazon Leadership Principle, requiring me to describe what I did in a given condition.

Preparation Tips

Some takeaways for others:

First, explain brute force and check that whether the interviewer has acknowledged that. I explained brute force, but had to again do it after providing the optimal solution, as I think I was not able to share my proper thoughts on it. The second question was unexpected due to having less time as I was not as close as choosing dp. And I had to explain the leadership question in a hurry and not able to properly explain each STAR principle as I merged action -> result -> action.
Ask a good question when they say "Do you have a question?"
