I applied through a recruiter. The process took 3 weeks. I interviewed at Amazon in Oct 2021
Interview
Recruiter contacted me, scheduled an OA then there were 4 rounds. Interviewer were great and helpful and in the end got selected. HR were not helpful and unresponsive, no body told me about the process, not replying to mails, forgetting to schedule calls.

3. Tell me about a time when you had a really tight deadline to get a task done.
4. Check if two strings after processing backspace character are equal or not
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.
