Working with Gaurav for my mock system design interview was a fantastic experience. He is an incredibly thoughtful mentor whose patience is truly exceptional. He doesn't just listen; he takes the time to fully understand the solutions you're proposing, creating a supportive learning environment. The set of questions he asked was spot-on and incredibly insightful, covering all the critical high-level components. Most importantly, his feedback was delivered with honesty and clarity.
