I am a Software Engineer with hands-on experience in backend development and a strong understanding of the interview processes followed by both service-based and product-based companies. Over the course of my career, I have appeared for and learned from interviews at multiple companies, which has given me clear insight into what interviewers actually look for beyond just solving problems. I started my career in a service-based organization and successfully transitioned into a product-based company. During this journey, I faced common challenges such as unclear preparation strategy, DSA consistency issues, resume shortlisting problems, and interview nervousness. By learning from rejections, refining my approach, and focusing on fundamentals, I was able to crack the switch. Now, I mentor students and early-career professionals who are aiming for backend roles or planning a service-to-product transition. I help with DSA preparation plans, backend interview concepts (Java, Spring Boot, REST APIs), resume improvement, mock interviews, and honest career guidance based on real interview experiences. My goal is to provide practical, no-fluff advice that actually helps you move closer to your next opportunity.
