In my first round, I was asked behavioral questions covering AI ethics, how I organize team activities, and how I resolve conflicts. The coding question was: Given a 2D matrix, find the longest path. You can only move up, down, left, or right. The next point m...
I was given an input string array and asked to write `encode` and `decode` methods. The `encode` method should encrypt the input and return a string. The `decode` method should decrypt the encrypted string and output the original list. For example: Input: `["f...
The phone screen consisted of two questions. **Question 1:** Given a string like `"12323#4(3)26#(2)"`, convert it to `abcwdddzz`. Parentheses indicate the number of times the preceding letter appears, and `#` indicates that the letter's index is two digits lon...
I interviewed with Nvidia for a chip testing position. An HR recruiter contacted me, and the process moved quickly, with the first interview scheduled within three days. The overall process includes three rounds, both online and in-person. Here's my experience...
I had a phone screen consisting of two coding questions, each with two parts. **Question 1:** A group of robots compete. The two robots with the highest scores compete, and their scores are offset, with the higher-scoring robot remaining. I was asked to determ...
Here's a breakdown of the ML coding questions I encountered during my onsite interview: **Round 1: Entropy Calculation** * Given logits, calculate entropy (using the log-sum-exp trick for numerical stability). * How would you calculate entropy online if logits...
I was asked to implement a simulation for a grid infection scenario. (1) Given an m x n grid with 'X' (infected) and '.' (healthy) cells, each day the infection spreads to all 8 neighboring cells (including diagonals). A healthy cell becomes infected if it has...
### Coding Round The coding question was: You have a [X]-hour layover in Paris and want to book some staying experiences. X here is a variable number of hours, rounded to a single decimal. While you are excited to try out new experiences, you prefer to book as...
### Phone Screen I was asked about key-value stores and refunds. I didn't perform well in the first round because my time complexity analysis was incorrect. Fortunately, the interviewer gave me a second chance with an additional interview. ### Onsite **Past Ex...
