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.
I applied through college or university. The process took 2 days. I interviewed at Amazon in Nov 2013
Interview
Resume given at campus job fair. The entire process consisted of 4 in person 1:1, 45 minute interviews at my school campus. First, an initial interview. If that one was passed, then they scheduled 3 more interviews with different interviewers over the following 2 days. The following day they extended me an offer. This was the same process for everyone who interviewed at my school.
Along with the offer, they invited me to fly up to the Seattle headquarters to see the site and meet with current engineers, have dinner, etc.
Somewhat strange as I was expecting the process they've done in the past, where they do an initial phone/on-campus interview and then fly you up for a full day of interview on-site.

Question 1
Nothing unusual or unexpected. Basic technical questions about linked lists, binary search trees, circular arrays, OO design. Pretty casual process actually.
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.
