I read everyone's interview experiences before and encountered the same questions, but I also made a lot of mistakes. This time, I'm giving back to the community and summarizing the questions for future interviewees. BQ: These are all fairly standard, just casual conversation. What was the most difficult project you encountered in your previous job? What AI experience do you have? Please elaborate. What are your requirements for your future team? The interview was for Senior+ level, and apparently there are still quite a few headcount points left. VO: There's a 3-hour and 90-minute option. Based on my research, the 3-hour questions are mostly the old versions, the one with the maximum concurrency fee; you can find the original questions everywhere. The 90-minute questions depend on the platform you're given; mine was codesignal. Then it depends on whether you're in Europe or the US (my guess). The format is generally four levels, with increasing coding difficulty. For example, level one might be writing a class. The European level seems to test on the bank system from LC and its evolved version. In the US, I encountered writing an in-memory database (cache). It's not actually that difficult; just search online (or ask chatGPT) and practice. If you really need the original questions, you'll need a Hire2Rank membership; search "Design In-memory Database". That's all. Good luck, and I'm hoping for some points!
