hey ankita,
Aricent is a leading company in IT sector. The atmosphere is extremely friendly and learning in this organization. The work at Aricent is also very good. The technologies are really good and especially if you want to learn this is the place for you. If you are looking for opportunities after this organization, than you can join HCL, Infosys, TCS, Wipro and so on. 3
If you have aricent than go for it because I have seen many people who prefer Aricent over Accenture.
