Visa Inc. Senior Java Developer interview questions

I applied for a contract position through a Recruiting company. Recruiter screened with a coding exercise followed by Telephonic screening and then Onsite interview. Telephonic had questions on Core java and other technologies I mentioned in my resume

I was being referred this job by Staffing Agency. They did my phone screen interview. Interview consisted of mainly technical questions. 3 guys took my phone screen one after another. All 3 guys were from different locations. One guy was happy with my interview but another was not. I was being told by Staffing Agency, that they need to take 4-5 interviews before making the decision. It took 1-2 weeks times. I told my staffing agency that I decline to take this position since they like to take too much time deciding and also I had others job offers in hand to decide. After next week, I got call from staffing agency that they like to have on-site interview with me. I ended up telling them that I already got job offer.
