The process is rigged. I don't even think they are interested in hiring. Most likely they just have job titles listed on their site for a "unicorn" that happens to pass by. I went through both a coding and architecture round. Both questions were not difficult. I went at the pace that the interviewers desired, balancing discussing over just spilling the answer onto the page.
I was given a no based on my performance on the coding round. The coding question was easy. They start by showing the first part of four-five parts. I asked the interviewer about the number of parts and pacing, They assured me to go at a casual pace, slowly test, etc. I got through the first 2 parts without any issues, doing multiple test cases while discussing.
Then after those 2 parts, the interviewer jumped to the 4th part and said let's verbally discuss it. He called it a "bonus." Again, I went through it without any issues and he agreed with my good implementation.
Most likely, they have jobs posted as a requirement for internal promotions or H1B hires. Don't waste your time interviewing here.
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.
Interview questions [1]
Question 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
I applied through other source. I interviewed at OpenAI (Dublin, Dublin) in May 2026
Interview
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.
