The interview process for the Software Development Engineer (SDE) role was structured and focused on assessing both technical and behavioral competencies. It began with an online assessment, which included data structures and algorithms questions. After clearing that round, I was invited to a series of technical interviews, where I solved coding problems in real-time using Python. The questions involved problem-solving, edge case handling, and time/space complexity analysis.
Additionally, I was evaluated on my understanding of core computer science concepts, such as object-oriented programming, system design basics, and debugging. The final stage involved behavioral interviews based on the company’s leadership principles and past experiences—covering scenarios like working in a team, handling failure, and ownership.

Question 1
Can you write a function to find the first non-repeating character in a string?"
This question tested my knowledge of data structures, particularly hash maps (dictionaries in Python), as well as my ability to optimize for time and space complexity. I walked through a brute-force solution first, then discussed an optimal approach using a two-pass algorithm with a dictionary.
I applied online. The process took 3 months. I interviewed at Amazon in Mar 2025

Question 1
Como eu lidei com tarefas que estavam foram da minha zona de conforto
It was a campus placement program. Amazon came and asked us to solve 2 programming questions. Most people (including me) were able to solve only 1. Amazon then chose people based on a criterion of their own, and proceeded with the interview process.
