The SDE interview was a thorough and challenging experience. It started with coding problems that tested my algorithmic skills and ability to write clean, efficient code. Then, I was asked system design questions to assess my understanding of building scalable applications and architectures. The interview also included behavioral questions to gauge my teamwork, communication skills, and how I handle pressure. Throughout, I focused on explaining my thought process clearly, discussing trade-offs, and staying calm under pressure. The feedback was constructive, and overall, it was a valuable learning experience.
