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...
I interviewed in January for a Machine Learning Engineer role. The onsite interview consisted of three technical rounds: - Two coding rounds (disease spread, Python version). - One ML round (classifier with different annotators). I initially received a positiv...
I recently completed the interview, but unfortunately, I was rejected. I want to share my experience to help others. **Coding Round:** The coding question was about an infectious disease problem with multiple parts: * **Part 1:** Given a matrix representing a...
### Phone Screen: - **Coding:** I was asked to implement a simple SQL query to query a database by name, age, and filter by ID. - **System Design:** I had to design a GitHub action system that supports many users and addresses scalability challenges. ### Onsit...
I had to debug a Transformer model, making sure it ran and produced correct loss and output. There were four bugs in total: 1. An error in the attention mask. 2. Incorrect parameter initialization. 3. A misplaced loss function calculation.
I was asked to model and simulate a physical system where a point light source emits particles towards an infinite vertical screen. A key aspect was sampling the scattering angle uniformly between -π/2 and π/2 to ensure particles reach all parts of the screen....
In the first round, I was asked to implement a string encoder and decoder, with the constraint that I couldn't use any special characters. The second round focused on designing Slack. I discussed the architecture and key features.
