Candidatei-me online. O processo levou 2 semanas. Fui entrevistado pela OpenAI (California, PA) em fev. de 2024
Entrevista
Going through OpenAI’s interview process was intense but rewarding. It started with an initial recruiter call, followed by technical interviews covering algorithms, coding, and system design. There were also problem-solving challenges and discussions about AI ethics, research, and real-world applications.

Pergunta 1
How would you design a scalable and efficient system for training a large language model, considering both computational and data constraints?
This whole process dragged on for about a month, much longer than I anticipated. It kicked off with a technical phone screen, where I was asked about data structures and algorithms. The DSA questions were tough, especially one regarding matrix traversal. Mid-way through the coding round, it clicked that I had tackled this exact problem on PracHub just days before, which helped me structure my answer. The onsite included system design questions that were challenging, but I didn’t end up receiving an offer. Overall, it was an intense experience.

Pergunta 1
Given an n x n matrix where each row and each column is sorted in ascending order, return the kth smallest element in the matrix. Walk through both the min-heap approach and the binary-search-on-value approach, compare their time and space complexity, and discuss which one you'd prefer for very large matrices that don't fit in memory.
2 rounds phone screen(1 coding + 1 system design) and 4 rounds onsite interviews(1 coding + 1 design + 1 deep dive + 1 behavior).
general good experience but need fast coding
Candidatei-me de outra forma. Fui entrevistado pela OpenAI (Dublin, Dublin) em mai. de 2026
Entrevista
Two hiring manager interviews. Followed by a technical interview on coding and system design. Asked to design a devbox system (CI/CD pipeline). For the coding roundm I was asked to design the LRU/LFU cache.
