How to do an internship when my college doesn't provide enough holidays?
Negotiation is the key! The duration range of a summer internship is 4-6 weeks and that of winter internships is usually 3-4 weeks. If you feel that you are falling short of the days to complete your internship you can directly negotiate with the employers. While interns can be beneficial for any organisation, the major challenge that most employers face is the time and energy they need to invest in induction/training. Maybe you can convince the employer for flexible work hours, or explain them the situation where you complete the internship without missing on your attendance.
Alternatively, if you have an offer letter from a good organisation, you can try convincing your HOD to provide you with a little exemption in attendance. Remember creativity is your best negotiation tactic in such situations.
