Five hours interview. Four interviewer all come from the same group. Each of them charge one round. There will have two questions each round, the first one is simple and the next one will be improve/refine the problem before. I believe if you are a bachelor always work with normal algorithms and data structures you will feel quite comfortable with this kind of interview. Graduate student is not necessary in this position. They only focus on your basic capability. I am graduate student and the intervire shcedule is not a good time for me. I perpare two days for this interview after my 3 final projects, I meet a issue when I hit the third round and ask for a hint, so i think I am not the perfect candidate in that group. I found that when they ask me to talk about my projrcts I feel that they are not that kind of "research guys". So again I think they are placing the emphasis on the basic capability...
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.
