H1B, H4 Visa

I have gone through various experiences posted in this forum which helped me and its time to post mine too. I work for xyz company in US and came to India recently for H1B stamping. I am from Hyderabad and I attended interview in Chennai (due to my convinience). There were few questions asked by the VO.
1. Name of the company?
2. How long have I been working there?
3. Compensation ?
4. Location?
5. What does the company do?
6. Do you have LCA documents.

Then the VO asked if I read the booklet of H1B employee rights, and I said No. He gave me a small booklet to read and stated that my visa has been approved.

My appointment was scheduled at 9 AM and i stood in the line at 8 45 AM and found out that people standing ahead of me had appointment time at 9 30 AM. I asked security guard if i was late, He just gave an expression and spoke in Tamil, all I understood from his expression is that "It doesn't matter".
1. There was one young lady VO who was getting really mad on one H1B aspirant who was not answering her question "About working at client or vendor location"? He tried to evade that question for which she got mad. I think She issued a 221 G ( Please note i am not sure and it's my guess as that happened 4-5 counters away from where I was standing). There was one old couple for Tourist visa and she asked same question 3 times loudly and issued visa eventually.

I hope my post will be helpful.

Thanks.
