I had an OA with 3 leetcode style questions. They were in the range of easy-medium. Then I had a standard 15 min recruiter call which asks me questions about my resume and to tell me about myself and why I am interested in Visa.

Not that bad. There is a general Codesignal and just one round of actual interviewing. It really depends on who is interviewing you, but it was 45 min of minor resume grilling with time for a technical question. There was a leetcode, but it was a super easy and took about 5 minutes. Not sure why it was included.
