Visa Inc. Developer interview questions

There are 1 OA, 1 coding round, 1 system design and 1 behaviour question round. The interview process takes 2 weeks and I keep asking update every 3 days. I pass all coding test but they reject me after final round. I think they want someone really good at selling what they have done in past projects.

Basic DSA and data engineering questions were asked in the PI. It consisted of 1 oa + 3 Tech Interviews + 1 HR. I was asked Dutch Flag algo and one question from file processor design.
