I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon in Oct 2012
Interview
Contacted by a recruiter through LinkedIn. After initial screening, they invited me to attend interview onsite.
Very friendly interviewers and I had lot of fun during the interviews. Interview consisted of 3 regular 1:1 interview + 1 bar raiser interview - each about 45 mins and about 10 mins for the candidates to ask any questions.
1. Very simple data structure question
2. How do you design type question. Lots of what if this happens and what are the assumptions type question.
3. Bar raiser interview: Another design type of question with lots of open ends.
4. Another design related question with respect to 3G technology.

Question 1
One of the interviewers is an expert in 3G technology. He posed me a question related to the inner workings of 3G technology. I am aware of how the internet works, TCP stacks, DNS, DHCP, and all that... I had no idea what kind of protocols are deloyed on 3G.
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.
