The coding questions were relatively straightforward. I needed to implement the Node class myself. **My approach:** 1. For the first problem, I used a simple recursive approach to sum the node values. 2. For the second problem, I used a recursive approach to f...

The HackerRank round consisted of two questions that required optimization to pass all test cases. **Question 1:** Given a permutation list and a value k, return true if, within the range of k, each value's corresponding permutation can be found as a subset in...
The problem involved multiple services that can be scaled up multiple times. Each scaling increases throughput but also increases costs. The input to the (i+1)th service comes from the ith service. The goal is to maximize throughput without exceeding a total b...
The interviewer introduced the problem as an infrastructure scheduling scenario. The question was Server Backup Scheduling: https://www.chillinterview.com/learn/coding-interview-questions/server-backup-scheduling. I was given backup jobs and timing constraints...
I was interviewing the staff-level position but got downgraded to senior-level
I was given a circular array `arr`, where `arr[i]` represents the number of steps I can jump left or right. Given a `from` and `to` index, I needed to find the shortest jump to get from the `from` index to the `to` index. I recognized this as a shortest path p...
The interviewer started by talking about internal tools and how employees navigate company structure. The question was Return Department Chain by Employee ID: https://www.chillinterview.com/learn/coding-interview-questions/return-department-chain-by-employee-i...
The question I received was: You are given an m x n integer matrix terrain, and an array limits of size k. You must compute an array answer of size k such that for each limits[i]: 1. Start at the top-left cell (0,0). 2. Repeat: * If limits[i] is strictly great...
## Preparation Tips & Key Takeaways ### What I Learned - The importance of speed, accuracy, and depth of understanding of metrics, especially for economics-related questions. - The need to clearly and concisely explain experiment designs and interpret results...
