The coding question I received was: ``` allocator(size=1000) malloc(size) -> pointer free(pointer) -> bool ``` The question was a memory allocator problem. Initially, I proposed a linked list solution with O(n) time complexity. The interviewer wasn't satisfied...

## Preparation Tips & Key Takeaways ### What I Learned - Ensure I am comfortable with standard data structures and algorithms. - System design interviews require understanding of real-world systems. - Practice behavioral questions to clearly articulate my expe...
In the first interview, due to technical difficulties with Google Chrome, I had to switch to Safari, which caused a few minutes of delay. Despite that, I managed to finish the question just in time. In the second interview, one of the four bugs was a subtle ty...
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...
Here's a breakdown of my OpenAI interview experience for a SWE role. **Phone Screen:** This was a 90-minute round that was split between coding and a mini system design, which surprised me. The coding question was about a real-time event aggregator: Given a st...
I just finished my coding interview. The two questions were quite different from those circulating online, and each question had an additional third part to elaborate on. 1. **Dynamic Human Labeling / Task Scheduling (Streaming + Daily Constraints):** You need...
## Round 1: React Coding I had to implement a ChatGPT-like interface in React, including basic message flow, an input box, loading states, and streaming responses. It wasn't extremely difficult, but required attention to detail in areas like state management,...
I encountered some questions that I hadn't seen on the forum recently, but I had practiced them all. The feedback I received in each round was consistently 'strong'. However, I was still rejected in the end, which I don't understand. **Coding:** IP Iterator. F...
