Unattended Internships

I got selected for a few internships, but I couldn't attend them because of overlapping academics or other commitments.
Some of them are:
  1. National Maritime Foundation (NMF) Spring Internship 2023
    NMF is a non-profit NGO dedicated to advancing India's maritime interests. I applied for a Maritime Cybersecurity research internship programme (SPRINGEX-23) for 6 months, and got selected!
    But the time period of the internship collided with my academic semester, not allowing me to attend this amazing opportunity.

  2. IIT Jammu RISE Research Internship 2023
    IIT Jammu is one of the new IITs in India. Research Internship in Science and Engineering - Undergraduate Program (RISE-UP) is a prestigious internship program for undergrad students.
    I applied for a research project on "Security of Smart Devices" under Dr. Gaurav Varshney, and got selected!
    But I had already accepted an internship offer from Irdeto, so I had to miss out on this opportunity.
