Lack of structure of internship, Interns try to find a project for themself 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 1 deadline. Don't expect to get full time offer after your internship.
