First-hand accounts from people who interviewed at TransUnion.
Software Engineer
I got interviewed through Campus Placements. About 150 people applied and took a test, and then 27 were shortlisted for the interviews. Depending on how well you did and how much time they had, there were 2-3 rounds. The first round was about my resume, DSA skills, and communication, lasting about 45 mins. It also included basic SQL questions like JOIN. The second round focused on my future plans, like whether I planned to do a Masters and why. They also asked me to design a model using OOPS concepts. I had a third round because I'm not from the city the office is in. This round had HR questions about my availability and a review of the interview process.
- Could you explain the implementation of two stacks and their respective complexities?
- Design a building facility center using OOPS concepts and provide sample code, explaining how the four pillars of OOPS are applied.
- Can you discuss your resume and DSA skills?
Senior Software Engineer
First round was a recruiter call to see if I was a good fit. Then, I had a call with the hiring manager. After that, the hiring manager and some people who would be my coworkers did a technical interview. There were big gaps between the interviews, and it took a really long time to hear back after I got rejected. Maybe they were seriously considering me?
- What makes you want to join our company?
Software Engineer
It was an on-campus drive. The first round was CV shortlisting, needing more than an 8 CGPA. Round 2 was an online test with English, Quantitative Analysis, and 2 coding questions (easy to medium difficulty). Round 3 was a Technical Interview where they asked me deeply about my projects, then asked me to write and explain the code for the Tower of Hanoi. They also asked me to write one basic SQL query, followed by general questions. Round 4 was HR cum technical; they'll tell you it's an HR round, but be prepared with your resume thoroughly. Make sure to learn whatever you've written on your CV.
- Could you write an algorithm to segregate even and odd numbers in an array, placing even numbers first and odd numbers subsequently?
- Can you determine if a given number is a palindrome?
- Please elaborate on your projects.
