Wipro Testing Engineer interview questions

I was placed under campus. There was a Aptitide, F2F ,and HR Interview. I was place in 2007 pas out batch . Should be stong in Aptitude. asked 30 C language Questions. 10 General knowledge and 20 aptitude kinda questions

They have no idea on organizing interview. They have asked everyone to report by 9.30 and no proper schedule has been made and people were waiting till 1 PM for first round. HR promised a different package while calling me for interview and after selected, they offer a totally different package which is just 10% hike. Why anyone would join for a mere 10% hike?
