I had attended Amitesh's Success Blueprint session. I felt good and confident about his guidance style. The session was scheduled for 30 minutes, but we continued for an hour discussing important interview topics. The best part I appreciated was that the session was free - he willingly provided his time and effort to guide me. He recommended specific topics to cover in Java, System Design, and Design Patterns, and suggested areas to focus on based on my experience level. He shared helpful resources for courses and practice questions to make my preparation more effective. Beyond technical aspects, he also guided me on the behavioral part of interviews and provided clear do's and don'ts.
