TransUnion Interview Experience (On-Campus)

Similar to the format of the coding round for the Trans Union coding assessment was conducted on a platform like Hacker rank. Candidates were allotted 90 minutes to solve three problems.

• The first problem was relatively straightforward, involving the calculation of the maximum area of a rectangle with 1’s at all four corners within a binary matrix.
• The second problem focused on the Word Break concept.
• The third problem delved into complex bitwise operations.

In the initial technical interview round, the interviewer primarily assessed the candidate’s problem-solving abilities. I was tasked with a practical problem: deleting the middle node of a linked list. Additionally, the interviewer asked some general questions about my background and experiences. While my interview lasted for 20 minutes, some candidates experienced longer sessions, with one being assigned the task of designing a complex system, akin to a ludo game (System Design).

Conducted by a panel of two interviewers, the second technical round commenced with an exploration of my internship experiences. Building upon this, I was presented with a problem related to finding the Next Greater Element in a Circular Array. Given my project in web development, the conversation naturally transitioned to database management. The interviewers probed into my choice of MongoDB, whether my database configuration was single-instance or multi-instance, and the functioning of URL navigation in a browser. Subsequently, I was asked to explain the ACID properties in DBMS with examples and discuss various types of joins in SQL.

Overall, the interview process at TransUnion mirrored the structure and depth of the interview experience. Each round provided a unique opportunity to showcase my skills and knowledge, underscoring the significance of preparedness and adaptability in technical interviews. #interviewexperiences #Experiences #WriteItUp2024
