SDE - 1

Duration: 90 mins. It was a machine coding round where candidates were given a problem statement which they need to solve within a given time. Problem Statement consists of 4 main questions and 1 bonus question. Candidates were supposed to code on their own machine/laptop. The main focus in this round was on Designing the System using OOPs Concepts and making the code as modular and scalable as possible.

(Tip: Follow high cohesiveness and less coupling principle while designing the system.)

Round 2:

Duration: 20-25 mins. Interviewers asked me to explain how I designed Memory allocator and which all sub-questions were implemented. I used JAVA as a programming language to implement the system. I explained to them the class diagram and abstract flow of the code. Then they started to go through the solution of each sub-question and tested different scenarios. Many cross-questions were asked as and when required. The main focus was to test the main functionality of the code along with testing modularity and scalability. Questions like what if I wanted to add/remove this functionality to/from this system? How much code change will it require? What are the other classes and methods which will be impacted? etc. were asked. I was invited for Round 3. Each round was elimination round.

(Tip: Don’t rush to complete the bonus question. The main focus was to test the core functionality of the system. The bonus question is cherry on the cake.)

Round 3: PS/DS (Problem Solving / Data Structures)

Duration 90-100 mins. This was an interesting round. Interviewers started shooting questions after a small intro session. I was asked to use pen-paper to write code for questions in this round.

Round 4: HM (Hiring Manager) Round

Duration: 30-50 mins. This round was interviewed by HM. I was asked to explain my past company projects in detail. A lot of cross-questions were asked to check in-depth knowledge about the projects and tech I worked on. Few behavioral questions like what was the biggest challenge in your past job? How did you overcome them? What was the strategy used? etc were asked. Apart from tech business questions were also asked to understand how clearly I understood the business. I was also given some insights on what the team (for which I was interviewed) works on and what all technologies are used by the team.
