Surprisingly easy — I expected tougher questions, but the coding round felt more like a warm-up. The main challenge was a DSA problem about counting islands in a 2D grid, which led to a discussion on DFS versus BFS and handling large grids. Funny enough, I had revisited that exact type of question while prepping on PracHub, which made me feel more confident. The interview wrapped up with a behavioral round, and I accepted an offer, but ultimately decided to decline it for another opportunity. Overall, it was a smooth experience.
Interview questions [1]
Question 1
Number of Islands — given a 2D grid of '1's (land) and '0's (water), count the number of connected islands. Walk through DFS vs BFS, and discuss how to avoid revisiting cells (in-place mutation vs visited set) and what changes if the grid is huge and must stream from disk.
I applied through a recruiter. The process took 3 weeks. I interviewed at Amazon (Atlanta, GA) in May 2022
Interview
1) Process started with a recruiter contacting me through LinkedIn. We had a general phone interview about the role.
2) Next steps were an online assessment. The online assessment consist of two easy/medium level leetcode questions.
3) Final step was an on-site virtual interview. Interview was consisted of 4 rounds.
Each round focused on a leadership principle with many follow ups.
Each round also had a technical portion. They are either object oriented design related to the position or medium/hard variation of leetcode.
Most of the interviewers are very friendly, but one gave a bad vibe. Recruiters were also very friendly and are very responsive.
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
Um teste de código online, se aprovado, vai para o loop. O loop é 4 entrevistas seguidas, duas em inglês e duas em português. 3 entrevistas técnicas de código, todas as 4 têm pergunta de liderança.
