Why this matters at interviews
Real interviewers don’t just check if you know the syntax — they probe whether you’ve used the concept under production pressure. Our drills mirror that. Adaptive difficulty, named anti-patterns called out as you go, and a senior-staff voice that teaches the production vocabulary rather than dumbing it down.
