Hello dear student,

No this kind of information can not be provided on this platform while if you want to check for the email ids and the telephone number of concerned you can directly check on the website of IIT JEE Kolkata University and there may be you can get the contact of the processes but try to contact them in a formal way where you put an email of your query if it's related to internships of working under them is concerned. otherwise if you are going to contact them for any other personal information I don't think so they will respond to your email.

Thank you
