Capital One interview questions

Surprisingly manageable — the interview felt more like a conversation than an interrogation. It began with a sequence of coding questions, including one on merging overlapping intervals. The real challenge came during system design, where I had to outline a URL shortener service that could scale impressively. Interestingly, I had just looked at a similar architecture on PracHub, which helped me articulate my thoughts clearly. The technical questions wrapped up with validating a binary search tree, and I ended with a positive vibe. I received an offer, but ultimately chose to decline it.
