## Preparation Tips & Key Takeaways ### What I Learned - I needed to focus on how AI can assist in solving coding problems, not just the algorithm itself. - I realized the importance of thoroughly understanding common data structures like LRU Cache. - I learne...
## Preparation Tips & Key Takeaways ### What I Learned - The AI round was challenging due to the large amount of code and difficulty in understanding what the interviewer was looking for. Rushing to answer can lead to misdirection. - AI can be helpful dependin...
My interview for the Meta MSL Paris team RS intern position consisted of two rounds, each 45 minutes long. **Round 1: Research** This round started with 5 minutes of small talk. I presented one of my research papers (the interviewer chose from two options). Th...
## Preparation Tips & Key Takeaways ### What I Learned - I learned the importance of being able to discuss multiple approaches to a problem, even if one is the most obvious. - Debugging and optimizing existing code is a valuable skill for AI/ML engineers. - Fa...
I had my onsite interview in early January. **Round 1: Coding** I don't remember the first question, but it was quite simple. The second question was random sample with weight, which I solved using binary search in O(log n) time. The follow-up question was how...
## Preparation Tips & Key Takeaways ### What I Learned - I learned the importance of understanding the underlying data structures when solving tree-based problems. - I also realized the importance of clearly defining the scope and constraints of a system desig...
The coding question involved a ticket query. The query included severity and timestamp. I needed to prioritize high severity tickets and the latest tickets. The solution needed to be able to update ticket information. For the AI coding round, I was fortunate n...
The phone screen focused on algorithmic problem-solving. One question involved using a heap data structure. Practice implementing heaps from scratch and solving problems that commonly use heaps. Also, review common algorithm patterns and time complexity analys...
I had a phone interview in November 2025 and after passing it, there was a system bug that prevented me from scheduling the onsite. After receiving the lowest performance review this year and being put on a PIP by my manager, I contacted the recruiter to arran...
