To be honest, I’ve done quite a bit of LeetCode, and while it’s great for practicing algorithms and problem-solving, I’ve found that I rarely use these “fancy” algorithms in my actual work. Most of the time, what really matters is breaking down requirements into clear logic, writing maintainable and collaborative code, and communicating well with the team. These skills are hard to assess through algorithm-focused interviews alone. I really hope interviews can place more emphasis on practical engineering skills and real-world scenarios, which would be more valuable for both companies and candidates.

I’m currently preparing for interviews myself, so having access to high-quality, free resources like this is incredibly helpful. The AI interviewer feature, in particular, looks like it will be very useful for me. Thanks again to the author for making these resources available!
