The HR will send a OA link to you, give you five days to finish it, then two Phone Interview. They talked with you about IQ questions, X,Y paper combination and follow up of six degree's space and time complexity

After applying, within few weeks they called me for phone interview.It is about 20 min. All friends who applied got interview call. But none got next round. The questions asked are same as given in liveramp. Need to brush concepts as after me gave an algorithm, he kept on probing about that algorithm, how do I do it, whether there will be any infinite loop.
