Visa Inc. Senior Testing Engineer - Automation interview questions

I have been called for the personal interview in AUSTIN after phone screening, I sat in a conf room, that place and office is not professional, docs are every where no security system. 2 people came inside and asked about my experience and all and asked about some QA methodology questions I did not exactly remember. After 45 mins of first round second set of two people came in to room and asked some questions of UNIX/API calls for 45 minutes he is asking tags and all and told me to write the structure on white board. After horrible 45 mins third set of two people came inside the conf room, asked some irritating questions like how to change directory in UNIX like that at some point I am completely tortured with basic PC questions. After 45 mins third set of people came to room they introduced as a developers they strated some questions in JAVA and JAVA script, I answered all the questions. All of sudden they started some QA questions again like what is blockbox testing..? I was so screwed and mad, I started there interview asking them which applications you develop? I started them asking questions JAVA, they thought he is doing reverse interview and left from the room. after 10 minutes one person came and told me that Manager is in California he wants to interview for 30 mins, Then I said "NO" and left from that place. .Please don't go for it, whether you get JOB or not literally you are tortured.
