It was quite long but very easy. Since I was placed just after I graduated, Interview was more about my academic and projects. We had an Aptitude test whose sample papers can be found on websites like freshersworld.com . Once the aptitude is cracked, group discussion was started. Topics included all the current world news. Then was 1:1 Interview (Only HR) . Since my B.E was in EXTC, but it was an IT Company, they asked mostly about my projects and academics and presentation skills.
