Selected Interview preparation journey
Journey
My journey into the world of technology started with building a strong foundation in core subjects like data structures, operating systems, computer networks, and databases. Initially, I focused on understanding concepts deeply rather than just memorizing them, which helped me develop problem-solving skills over time. Alongside academics, I worked on practical projects using Java and Python, which gave me hands-on exposure to real-world application development.
Application story
I applied for the role through an online application portal. After applying, I went through an initial screening process followed by further interview rounds. The overall process was smooth and structured, focusing on both technical knowledge and practical understanding. I made sure to prepare consistently during this phase and revise core concepts along with my project work.
Why selected/rejected for the role?
I was selected because I had a good balance of strong fundamentals and practical experience. My understanding of core subjects like DBMS, OS, and Computer Networks was clear, and I could apply that knowledge while discussing my projects. I also focused on backend development, APIs. which aligned well with the role. Additionally, I was able to communicate my thoughts clearly and explain my work confidently, which helped me stand out during the interview process.
Preparation
Duration: 6 months
Topics: Data Structures, Algorithms, Object-Oriented Programming (OOP), Operating Systems, DBMS, Computer Networks, REST APIs, Distributed Systems
Tip 1 - Build strong fundamentals in core subjects like DBMS, Operating Systems, and Computer Networks instead of only memorizing interview answers.
Tip 2 - Work on real-world projects using Java, Python, and AI-related tools to develop practical understanding and confidence.
Tip 3 - Practice explaining concepts like REST APIs and system architecture clearly, because communication matters as much as technical knowledge in interviews.
Application process
Where: Campus
Eligibility: Above 7 CGPA, (Stipend: 30k per month)
Tip 1: Add 1–2 strong projects that demonstrate real-world skills (backend, APIs, AI) and that you fully understand end-to-end.
Tip 2: Only include skills and technologies that you can confidently explain in depth during interviews.

Coding problem1
In this round, I was asked questions on core concepts of OOP, DBMS, and Computer Networks to check my fundamentals. The interviewer also discussed my ML project on diabetic prediction and asked a few questions related to its implementation and approach. Additionally, I was given one medium-level DSA problem to solve.
Timing: Evening around 4 to 5
Environment: Calm and professional, no pressure from interviewer
Interviewer: Friendly and supportive, gave hints when required and focused on understanding my thought process
1. House Robber II
Moderate

Asked in companies
Mr. X is a professional robber planning to rob houses along a street. Each house has a certain amount of money hidden.
All houses along this street are arranged in a circle. That means the first house is the neighbour of the last one. Meanwhile, adjacent houses have a security system connected, and it will automatically contact the police if two adjacent houses are broken into on the same night.
You are given an array/list of non-negative integers 'ARR' representing the amount of money of each house. Your task is to return the maximum amount of money Mr. X can rob tonight without alerting the police.
Note:
It is possible for Mr. X to rob the same amount of money by looting two different sets of houses. Just print the maximum possible robbed amount, irrespective of sets of houses robbed.
For example:
(i) Given the input array arr[] = {2, 3, 2} the output will be 3 because Mr X cannot rob house 1 (money = 2) and then rob house 3 (money = 2), because they are adjacent houses. So, he’ll rob only house 2 (money = 3)
(ii) Given the input array arr[] = {1, 2, 3, 1} the output will be 4 because Mr X rob house 1 (money = 1) and then rob house 3 (money = 3).
(iii) Given the input array arr[] = {0} the output will be 0 because Mr. X has got nothing to rob.
Problem approach
Step 1: First, I clarified the problem with the interviewer and explained that since houses are in a circular arrangement, we cannot take both the first and last house together.
Step 2: I broke the problem into two linear cases:
Case 1: Consider houses from index 0 to n-2
Case 2: Consider houses from index 1 to n-1
Step 3: I applied the standard House Robber (DP) approach on both cases, where for each house I decide whether to take it or skip it based on maximum profit.
Step 4: I computed the maximum profit for both cases and returned the maximum of the two results.
Step 5: Finally, I dry-ran the code with sample inputs and explained the time and space complexity to the interviewer.

In this round, I was asked about core Java concepts such as Strings, Streams, and exception handling to evaluate my understanding of the language fundamentals. The interviewer also asked a few DSA-related questions to test problem-solving skills. Additionally, my knowledge of MySQL was discussed, including queries and database concepts. The overall focus was on both theoretical understanding and practical application of concepts.
