Visa Inc. Sr. Software Engineer interview questions

Invited to the job fair to apply and talk about opportunities. Recruiter, manager or HR was not present. Interviews conducted by various engineers, even recent graduates, for different roles. It was hard to tell who was interviewing for what roles. Few asked me to go talk to someone else. Not clear if there was any interest, or what the next steps would be. New graduates and junior programmers seems to be more lucky.
