Sessions with Sachin Gupta

• General Mentorship Session (30 min): General Mentorship Session
• System Design Interview Mock Session (60 min): In this 60 minute mock system design interview, we’ll work through a realistic system design question in an interview style setting. The focus is not just on reaching a solution, but on how you approach the problem, ask clarifying questions, make tradeoffs, and communicate your thinking. You’ll receive specific feedback on: • Understanding and scoping the problem • Asking the right clarifying questions • Structuring your approach • Explaining design decisions and tradeoffs • Communicating clearly while thinking through ambiguity After the interview, we’ll review what went well and where you can improve. You’ll also have a chance to retry the part you found most challenging and apply the feedback immediately. We’ll finish with a few practical next steps to help you prepare more effectively for your upcoming system design interviews.
• Coding Interview Mock Session (60 min): In this 60 minute mock coding interview, you’ll work through two coding problems in a realistic interview setting. The focus is not just on getting to the correct solution, but on demonstrating a clear and structured problem solving process. We’ll practice: • Understanding the problem and asking clarifying questions • Breaking the problem down and explaining your approach • Discussing tradeoffs and complexity • Writing clean, correct code • Testing your solution and handling edge cases • Communicating your thinking throughout the interview After each problem, I’ll provide specific feedback on your problem solving, coding, and communication, including what went well and where you can improve. We’ll finish with focused, practical next steps to help you prepare more effectively for your upcoming coding interviews.
• Behavioral Interview Mock Session (60 min): Behavioral interviews are often overlooked compared with technical or case interviews, but they can be just as important. This 60 minute mock interview is designed to help you practice in a realistic setting and get actionable feedback. What to expect We’ll simulate a behavioral interview with realistic questions, follow ups, and situations you may encounter in an actual interview. I may dig deeper into your answers or challenge you to clarify your thinking, just as an interviewer would. Afterward, we’ll review your performance and discuss: • How clearly and concisely you communicate • How well you structure answers using STAR or similar approaches • Whether your examples demonstrate impact, ownership, collaboration, and decision making • How you handle follow up questions and unexpected situations • Specific areas to strengthen before your next interview If you have an upcoming interview, bring the role or job description so we can make the session more relevant.
