Selected Interview preparation journey
Journey
I began my coding journey during my M.Tech at IIIT Delhi, where I built a strong foundation in computer science and programming. I delved into AI, ML, and cloud technologies, working on projects such as a Virtual Try-On app and contributing to credit card fraud detection. By consistently solving over 600 problems on coding platforms. I sharpened my skills. These efforts helped me secure a position as a Power Programmer at Infosys, which further enhanced my technical expertise and confidence, ultimately enabling me to successfully crack the interview.
Application story
Infosys visited our IIIT Delhi campus for recruitment. The process began with a three-hour online assessment (OA) that included three challenging coding problems. After successfully clearing the OA, I was shortlisted for an interview. The interview took place on-site at Infosys' Noida Development Center (DC) and focused on both technical and problem-solving skills. I showcased my knowledge and hands-on experience from various projects. The entire process was rigorous but rewarding, ultimately leading to my selection as a Power Programmer at Infosys.
Why selected/rejected for the role?
I was selected due to my consistent practice, having solved around 600 DSA questions on coding platforms, which gave me a strong understanding of algorithms and problem-solving. Additionally, my solid foundation in OS, DBMS, and SQL queries proved helpful during the interview. I also highlighted the hands-on experience gained during my M.Tech, where I developed 3–4 significant projects in AI, ML, and web development. These projects showcased my ability to apply theoretical knowledge to real-world problems, which played a crucial role in securing the position. The key takeaway: consistent practice and building real-world projects are essential for success.

Asked in companies
You have a given 1 int array. You need to separate this array into 2 subarrays s1 and s2. After that do a summation of both subarrays so the summation of s1 is sum1 and summation of s2 is sum2. So you need to select 2 subarrays in a manner so that the mod of sum1 and sum2 is minimum.
Problem approach
Step 1: First, take the summation of the entire array.
Step 2: Now, divide the summation by 2 and use it as the target value.
Step 3: Find a subarray whose sum is closest to that target.
Step 4: I used dynamic programming (DP) to solve this problem.
