Lack of structure of internship. Interns try to find a project for themselves in the first 2-3 weeks of internship. They are not clear what they are expecting from the interns.

They will say things like, "Take it chill, there is no rush, you can postpone deadlines no worries" in the beginning, and at the end of the internship, you will be grilled for postponing one deadline.

Don't expect to get a full-time offer after your internship.

Get a structure for interns and decide on the projects before interns join.

Clearly state in the first week what you are expecting from interns and if there is a possibility for a full-time offer. Be honest. Be clear.
