Zeta(Directi) Interview Experience for Senior Software Engineer

I have worked in various product-based MNCs or startups so far but to reach there I have gone through multiple companies’ interview sessions which I am very happy to share with you all. If you are preparing for an interview may be to the same company or one that has similar requirements can get an idea about the interview question and process through my article. Recently I got interviewed in multiple companies and took one company as the final one but the journey is still on to achieve the dream company.

So for this company recruiter Approached me via LinkedIn message. And interview journey was as follows:

Technical Round 1:Problem solving(DSA)

• Print all permutations of a string in Java
• House Robber

Above I have attached the problem and solution to it. I was able to solve that in the interview so appeared in the second round.

Technical Round 2: Low-Level Design Question

1) Design a Bus Booking System – like the Redbus

• getBusDetails(): Returns details about the bus.
• checkAvailability(): Checks the availability of seats on the bus.
• bookSeat(Seat seat, Passenger passenger): Books a seat for a passenger.
• cancelBooking(Booking booking): Cancels a booking and releases the seat
• makeBooking(Bus bus, Seat seat, Passenger passenger)
• Solve Multi-Stop Booking

Technical Round 3: High-Level Design Problem

1) Design Multiple Task Management System (Scheduler)

Design a Java-based Multiple Task Management System that allows users to create, assign, and track tasks. The system should support task prioritisation , deadlines, status updates, and user authentication. Implement classes for tasks, users, and a management system to handle task operations.

This is something that takes my head up and the discussion goes on beyond the set limits.

Cultural and Fitment Round: Hiring Manager Discussion

• Discussion – Past Projects
• Some questions about distributed Systems and services

Overall I can say there are questions asked on the set criteria and meeting up the position responsibilities they are looking for.

If you do have queries about it either can comment here or can connect with me directly on Linkedin. I will try to create solutions in a simplified way to these questions what cross-question in between of the session I came across for the given solution. So stay connected.
