Onsite. You need a little luck to get a nice/good interviewer.
In one round, the interviewer was very vague, did not provide input/output. When I asked him to clarify the question, he stayed silent...?!? When I made up the input, it didn't match what he had in hand. He kept quizzing me "why do you choose this input?", and never gave me the input throughout the entire interview. My input should work, it was just not what he was looking for. The problem was not hard. But since I didn't have the correct input, I didn't have the implementation he wanted to see.
In another round, the interviewer gave me <25m for the coding part, but keep expanding the question. I couldn't finish all cases within the time limit.
In 2 other rounds with nicer interviewers, they communicated well with me and I did ok.
Rejected in the end.

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.

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.

Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.

The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
