Entrevista
Applied the SDE position online in October and waited for an interview for 3 month. In mid January, I received the email for phone interview arrangement. Interview has two back to back 45 mins interviews, but after I finished the first one, the recruiter rearrange the second interview to the next day. Both interviews are technical, and there are 4 questions in total. Still waiting for the result.

Pergunta 1
1. Given a number (not necessarily of type int), find if it is 2^n. What is the complexity?
2. Given a set of points represented by x and y coordinates, find out the first k points that are closest to the origin. What is the complexity?
3. Given an array of integers, return the largest occurrence element times its array index. Do it in place. What is the complexity?
4. Given a binary tree(not necessarily BST), return the sum of all kth level nodes. What is the complexity?
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.

Pergunta 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.

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.

Pergunta 1
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
