Hi,

I believe you are looking for entry level IT jobs. TCS generally conducts off-campus drive in the month of December and the registration for the same is open in November. Dates are to be announced. Registration for Wipro ends on 30th March, 2019. But 2019 pass outs are not eligible, their exam dates will be released later. Infosys usually conducts interviews in the month of August and September. Cognizant (CTS) usually conducts tests between January to April.

Hope this helps.

Cheers!
