Online Assessment(2 hrs)

There were 3 questions from number theory, graph, and DP(One question from each topic). Questions were on a medium-difficult level. I was able to solve all the 3 questions in 45 minutes.

Data Structures/Algorithms Round(1 hr):

The interview began with a standard introduction with two interviewers. Following that, they presented me with two questions to solve, allotting a one-hour timeframe. The initial question was a Leetcode medium-level problem based on binary search, and the second involved strings and permutations, which was a Leetcode hard question. I successfully solved both problems with optimal complexities in 40 minutes. The remaining 10 minutes were dedicated to a casual discussion about Zeta and its work culture.

Computer Science Fundamentals Round(1 hr):

This round again had two interviewers, and I started this round with my introduction. The conversation then moved on to discussions about my projects, lasting for about 10 minutes. Subsequently, the interviewers shared a Google Doc link, and asked me to explain and code writing for all four pillars of Object-Oriented Programming (OOP). They focused much on the run-time polymorphism part and asked deep questions on that part. Then the asked questions on exception handling, try-catch blocks, and SQL-related questions, involving both joins and subqueries. The discussion then moved on to operating systems, with questions about deadlock. Towards the end, I asked about their roles in the Zeta and my potential responsibilities if I were to be hired.

Fitment Round(30 mins):

Upon clearing the Computer Science fundamentals round, I learned about the next round scheduled for the following day at 10:45 AM. I prepared for general HR questions, I revisited my projects and technical concepts. The interview started off with an introduction from the interviewer, followed by my self-introduction. We discussed my projects, and I was cross-questioned on my projects and internships. The conversation then shifted to situational questions regarding the company, teams, and conflict resolution. Additionally, I responded to typical HR-related questions, such as future aspirations and reasons for being a suitable candidate. After 30 minutes, the interviewer expressed satisfaction, and I took the opportunity to ask questions about him and Zeta.

Tips and Recommendations:

Maximize the time before your interview by utilizing every available minute. Ensure thorough revision of your concepts beforehand. Strategically plan your preparation, determining how and what you will study prior to the interview. Avoid cramming and aim for a comprehensive understanding of each concept, enabling you to code proficiently when needed, be it OOP concepts, DS/Algo concepts, and more. Review your resume nicely, ensuring that you know everything mentioned in your resume. Develop a good understanding of your projects, as they reflect your work and serve as a reliable source to judge you. Actively engage with the interviewer during the interview and at its conclusion. Pose questions about the company and its work, demonstrating your enthusiasm to join and leaving a positive impression on the interviewer.
