Lenskart Solutions Software Engineer Interview Questions
& Process

It was a bit tough to get through and requires a solid understanding of coding fundamentals and design patterns. There was one technical round where we coded, and then an HR round. My interviewer was great, and we had a good discussion while coding.

So the interview took about two weeks and had 4 rounds in total. It was a pretty good experience overall, even though I didn't get the job after the last round. Apparently, they were looking for someone absolutely perfect. The first round was all about coding questions and some Java core concepts. The second round was in person and focused mostly on tree-related problems. The third round was also in person, and we went into more advanced topics like caching, system design, design patterns, and of course, more tree questions. The final round was the managerial one, also in person. This one was heavily focused on system design, thinking about things like how to handle simultaneous updates in a Google Docs-like system and how to generate itemized bills for servers based on their usage.

Applied via employee referral. The whole thing took 1 day at Lenskart Bangalore. The first round was a programming test on paper with about 15 snippet codes and 2 programs on arrays, plus designing a parking lot. After passing the first round, there was a second round. In the second round, the interviewer didn't seem to know Java or what questions to ask, he was looking at Google and asking questions. He asked a few basic questions on collections, threads, exception handling, and data structures. I answered everything correctly, but later they gave negative feedback. It was a waste of a full day with some clueless person interviewing me. If they don't want to select someone, they shouldn't waste their time calling them for an interview.
