Unilever Payroll interview questions

My First Telephonic interview happened sometime in May 2016 after 2 months I got a mail from recruiter saying they want in person interview with 3 different persons for 3 hrs. Interview went very well, answered all the questions & scenarios. After a week recruiter called and say they are looking for some other person. Asked for specific reason, they are not able to tell me, recruiter told me that they liked my profile, experience the way handled the problems, compensation is also not a reason, not sure why they rejected me
