Mindfire Solutions Software Testing Engineer interview questions

I was called for the first round. HR called me and told you will have one programming round. It was for 2 hours. After completing he told to wait for some time while he needed to evaluate my performance. After some times another executive came and told you may leave for the day. After having some discussion with her she came to know that they gave me wrong question paper!!! I was supposed to go through aptitude exam while he gave me programs by mistake. Because he THOUGHT that I was being interviewed for developer post. Again they called me and gave me one system and 3 passwords for 3 exams. This round was aptitude round. Anyhow I was compelled to appear the test after three hours of confusion and frustration. Though questions were easy I was unable to attend some questions because of blocked mind due to hunger and anger. LOL my exam time was 12 pm. But my actual exam started at 5 pm. What was I doing for 5 hours ??? For first 1 hour I waited for hr.Next 2 hours I appeared one exam irrelevant to my profile. Next 2 hours waiting for the result, discussion, doubt clear and all.
