The interview process involved three rounds:

• One telephonic interview
• Two face-to-face interviews

Recruiters were unprofessional. Interviews were delayed from the scheduled time by 1.5 hours. I was forced to come on a weekday for a 3-hour interview and ended up staying for 5 hours.

The interviewers seemed uninterested and appeared to be conducting the interview merely for the sake of it.

My sincere suggestion is to avoid wasting your valuable time by attending interviews with Visa. They lack basic courtesy and did not inform me about the interviewer's unavailability. They also did not provide feedback via email or phone, even after I spent over 4 hours interviewing.

General scalability and system design related questions.
