Visa Inc. Staff Software Engineer interview questions

It all started with hackerrank test , followed by Senior Director Interview , 4 rounds of technical Interview , 1 additional Interview , 1 Interview with Director .

Horrific interview experience @ Bellevue (WA) office few months back. Recruiter directly scheduled full-day onsite without a call. Nor was there an informational with a manager or any phone interview. This was a red flag but I anyway showed up. Onsite there are 4 hrs of interviews scheduled with 8 interviewers(?!) The first was with Hiring manger who never showed up - shocking.!! A tech lead shows up and get I all random questions - 'why didn't you apply for this other role' and the demeanor was mostly mocking - 'what do you know about x'.. After a few random questions for 10-15 min, the interview ends. After that 2 proper coding interviews happen but they are for around 30-35 min. After 2 hrs of interviewing I am all of a sudden asked to leave?! My interviews weren't bad IMO and it seems impossible to be based off of that. Either they found a candidate already or something else happened. After the onsite the recruiter never emails back anything - not even thanking for showing for an abrupt onsite interview? Even after a ping the recruiter does not respond. (recruiter was ignoring questions email questions before the interview so perhaps its expected) Can you believe this behavior? Sheer arrogance. They need to lean to treat external candidates respectfully.
