Best advice.. go for as many interviews as possible.. gain experience then no longer need to worry..

Myself going for my 1st full time job.. went for more than 20 interviews.. even went for some which I didn't really wanted (just for the experience and to gain knowledge of the particular job scope and industry).. eventually got more then 50% success of landing a job but sadly the ones that suited me best were the earlier interviews when I wasn't certain on the job or didn't like the 'package' or wasn't prepared enough.. Luckily found one at last.. Haha

Some advice, for freshie: usually about urself; family, background, education, ambition, character, personality and depending on ur interviewer you will usually be given questions that will test your creativity, temperament, maturity, analytical, computational and critical thinking skills in either informal way (leisurely given question) or formal way (part of a set interviewing process questions)..

What kind of questions?? Depends on the company and interviewer.. No 'set' questions.. This aint a school like subject were there are 'correct' and 'incorrect' answers.. Depends on each individual.. Best way is to try and visualize urself as the employer and think what you will ask ur potential employee..
