My interview experience at OpenAI involved a phone screen and an onsite interview. **Phone Screen:** * Coding: I was asked a contagion problem similar to one I'd seen before in this platform. The questions progressed in difficulty: 1. How long does it take for...
The coding question I got was: You are working with a toy language grammar that supports three kinds of types: primitives, generics, and tuples. This system is used for defining function types, including parameter and return types. - Primitive types: "int", "c...
The first technical round involved a transformer debugging question. I had prepared by reviewing related posts and Karpathy's YouTube course, and practiced with GPT-generated bugs. I caught the four bugs quickly. The follow-up question was to change it into a...
I interviewed for a Machine Learning Engineer role. I was rejected after the full loop. **Round 1: Coding (60 minutes)** The question was a Cellular Automata / Pandemic Simulation problem with 5 progressive parts: 1. Basic: Simulate virus spread on a plant gri...
I recently interviewed and the questions were commonly asked in interviews. **Round 1:** 60min ML coding. I implemented 1NN using NumPy, and then rewrote it in the form of neural network weights. About a week later, I was notified to schedule the next three ro...
I was provided with starter code and test cases, which I could view. Running unit tests showed the number passed, and I could see failure cases. My understanding is that the key is to quickly solve the problems with code that's easy to write and uses simple me...
The coding question I got was: ``` /* This is a provided API class. */ class VersionChecker { /** * @param version A version string. * @return true if the version is supported, false otherwise. */ public boolean isSupported(String version); } ``` Implement the...
## Preparation Tips & Key Takeaways ### What I Learned - I need to be very comfortable with implementing social network features. - System design questions require a broad understanding of different components. ### Recommended Preparation #### Coding Practice...
The coding question I got was: ``` You are implementing a shard management system for a distributed key-value store. The system distributes data across multiple shards given in the format "<id>:<start>:<end>". Each shard is responsible for a contiguous range o...
