What’s the avg tax internship like?

I'm graduating next year with bachelors in accounting. Been in contact with Deloitte about a tax internship next summer (after graduation, before grad school). Just wondering what I could expect out of a tax internship there or at the other Big4.  (Hours, responsibilities, pay,etc) I have a 3.74 gpa, honors, and have experience as a legal assistant so I'm not too worried about getting the internship but let me know if I should be!
