The process took 4 weeks. I interviewed at Amazon in Dec 2010
Interview
Recently went through a really long interview process with Amazon which ended in no offer. The process included 3 phone interviews and as per me, I did well in them. I may have taken a little long on some common (still tricky questions) as I haven't looked at them before but in the end I did manage to come up with a solution on my own with some hints from the interviewer. Apart from this, I really can't see any other issue as most other questions I already knew solutions for. I was really hoping for an onsite interview opportunity but instead got a reject.
I know amazon have some high bars for their positions but from this process, I really can't make out where I fell short. Anyway will try again in future.
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.
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.
