Solved 300 LeetCode Problems but Still Freeze in Interviews? It's a Rehearsal Problem

The article explains why simply solving 300 LeetCode problems may not be enough for acing a technical interview. It highlights that the interview setting adds a new layer of pressure not present in solo practice. A 2020 study showed that when students solved problems alone on a whiteboard versus explaining them to an interviewer, the latter group performed significantly worse, with higher stress levels.

The author argues that the key to success lies in practicing the actual interview conditions. They suggest four key drills - narrating every practice problem from start to finish, learning to navigate moments of blanking out by sharing what you know, practicing being watched through full mock interviews, and repeating this process multiple times in the final weeks before the interview.

They also provide several options to get the necessary practice experience, ranging from free tools like DevInterview.ai that give a recorded voice interviewer, to paid services like interviewing.io that connect you with a human interviewer. The author recommends doing most practice sessions out loud, supplementing with a single paid human session near the actual interview date.

In summary, the piece argues that while solving many LeetCode problems is a good first step, the real hurdle is learning how to solve them out loud under pressure - which requires specific rehearsal drills and full mock interviews designed to mimic the real interview conditions.
