Popular Bank Interview Questions
& Process

I had a software role interview with three parts: data structures and algorithms (DSA), system design, and behavioral questions. For DSA, I tackled a sliding-window array problem and a graph traversal, discussing edge cases and Big-O notation. The system design portion involved sketching out a URL shortener, covering API endpoints, ID generation, database schema, caching strategies, replication, rate limiting, and monitoring, while also explaining the trade-offs between consistency and availability. The behavioral part focused on teamwork, how I handle mistakes, and giving/receiving feedback, using the STAR method. Throughout the process, I made sure to communicate clearly, demonstrate testing approaches, and explain my reasoning.

My interview with Popular Bank involved a phone chat, an online video call, and finally meeting the branch managers in person. Each part was about an hour long and mostly behavioral questions. A lot of the questions didn't seem to connect with what a teller actually does. The whole thing felt unorganized and not very professional. Communication was really slow and bad; I had to chase them for updates and often my emails were ignored. I ended up calling HR to get any info. During the in-person meeting, the managers trashed a former employee right in front of me, which was super unprofessional. It left a bad taste, and even if they offered me the job, I wouldn't have taken it. There are better banks out there.

It started with a quick Teams chat to get to know me, asking about my background and why I'm interested in the job. Then, I had to do an online test for about 2 hours, covering general problem-solving and basic tech stuff. If you pass that, you go on to talk with the actual team you might join. Pretty organized process overall.

My hiring experience at Banco Popular was really easy. After applying, I got quick replies all the way through. They also gave me good training and easy-to-follow manuals, so I felt ready for the job. It was clear they care about helping employees grow, which made starting there smooth. Overall, the whole process felt fast and organized, which says good things about working there.
