Easy Positive India

My first round was an MCQ test in a Google-form style layout, and it ran about 45 minutes with 50 questions. Even though it felt manageable in the moment, the topics were broad enough to keep me focused: DSA, operating system concepts, SQL/DBMS ideas, and networking. The questions often came in code-snippet formats, so I had to interpret small pieces of C and DSA-related logic rather than just recall definitions.

After the MCQ, I moved toward technical discussion and an HR round. The technical parts emphasized core fundamentals and how I thought about OOP concepts, not just what syntax I could recite. I remember feeling that the interviewer was satisfied with how I explained my understanding.

Difficult Negative India

The process started with an online aptitude-style assessment. It covered basics like mathematics, reasoning, and logic, and I kept moving through questions fast enough to stay on track. After that, there was a coding round with five questions, where the expectation was to clear most of them—around four and a half to be in contention. The overall structure felt like it was designed to filter people pretty aggressively.

Next came multiple technical rounds tied to projects and internships, followed by an HR round. I remember the coding portion as the most concrete hurdle, and the difficulty was high enough that I was constantly thinking about whether I was spending time in the right places. End to end, it felt like a multi-step pipeline rather than a single interview, and by the time I reached the final stages, the result still didn’t go my way. I was disappointed by how quickly the earlier thresholds seemed to decide things.
