Hi Madhu,
I think kunjal as explained to you everything for you short. According to me it can change a little depending on the company policy, here i would like to add one point. After the exit interview is completed and all the related documents are collected back from the employees than it will be always better to send out a mail to the team in the which that resigned employee was working, this will ensure you that the team will no more hand over any documents on last day in case of any urgency and more over the team will be alerted not to share any information with that particular employee.
Let me know in case you have any clarifications on the same topic.
Regards
Amith R.
