The first-round technical interview consisted of 25 challenging questions, making it both nice and difficult at the same time. The interview was designed to test a wide range of technical skills, including algorithms, data structures, problem-solving, and system design. The questions were thought-provoking and required not just theoretical knowledge but also the ability to apply concepts in practical, real-world scenarios. Some questions were straightforward, while others were more complex and required deep analytical thinking to solve efficiently. The interviewer was thorough and patient, encouraging me to explain my thought process at each step, which made the experience very engaging. While some questions tested my knowledge of core principles, others pushed me to optimize my solutions for performance and scalability. Overall, it was a great learning experience, and I felt it was a fair test of my technical ability
