Zycus Reviews for senior consultant role

My sister works in EY. Can anyone share a genuine suggestion on whether she should accept the offer from Zycus for the role of Senior Consultant in the Consulting ( SSG ) domain if she is getting max 28 lpa approx (including everything) and currently she is having a ctc of 21 lac in EY. I feel she will have better learning considering in EY she was working only with Order to Cash domain but in Zycus she will get the exposure to S2P and P2P
