Infosys Software Developer interview questions

Got approached for infosys opening through a recruiter. Fixed interview on a saturday at Infosys campus. Well it felt like a walkin drive although i was promised a scheduled time for the interview. I waited for some time then walked off as it did not make sense to me to wait for so long in a walkin.

1st stage aptitude.. and then PERSONAL INTERVIEW.. FOLLOWED BY SERIES OF TECHNICAL TEST.. AND INTERVIEW..well college took all the responsibility of calling the company and asked them to provide job opportunity.. it was good experience . i have to fill 50 words in this paragraph.. God knows what am i going to write.. and why the hell are they asking me to write so long.. when i can explain in jst few words
