I applied through a recruiter. The process took 1 week. I interviewed at Amazon (Seattle, WA) in Dec 2011
Interview
I got a email from a recruiter after I posted my resume on Dice.com. Went through two phone interviews. After the first interview got a date for a second however it got rescheduled due to a scheduling error. Just my bit of advice from the experience so far, be confident of the answers you give even during coding.
Interview questions [2]
Question 1
First phone interview
Given a node find all leaves belonging to its children.
Second phone interview
Think of an organizational structure where each employee is reviewed and given points. Could be any integer. If doing good positive, if not negative, if neutral then 0.
Now find the node with the highest number of points when adding points belonging to it and all its children.
3
4 7
0 6 2 -50
In this case the answer is Node 4
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.

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.
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.
