A company conducts campus placement in about 10 to 12 colleges. Overall they shortlist about 100 to 110 students from all the colleges and calls them for next round of interviews. After over 2 to 3 months of drama they provide offer to 10 to 15 students just in case if someone backs out. The position and salary is not that great but for a fresher its an average pay job with average skills required for that job and any graduate with average score can do the job. So why waste so much time ? This is not a one-time deal they do this annually ? Is this normal or they just do it so the HR has something to do for that period ? Why waste so much resources for this ?
