Cognizant — not receiving interview call letter

Sent multiple emails to sridevi. [protected]@cognizant.com but received no response so far for an interview call.
The job role suits my profile and should have been considered for an interview. But even after sending multiple emails to sridevi, received no response.
Hr team should learn email etiquette.
If experience people like us faces such issues, i really dont know what kind of attitude they show towards freshers or less experienced folks.
