Sun Life Manual Testing interview questions

I gave written round, then technical and personal rounds (2). All of them were cleared. They say they selected 3 people for 2 vacancies. and after final round which was just a formality round. I was asked to leave. No logic or anything was given. After giving 3 successful rounds they evicted the candidate to the final into round with head. Sheer wastage of time. If you want to hire only references candidates please don't waste time of other candidates. Not a good experience with such a big company. Only go if you have reference else you will waste your time even you cleared all your rounds.
