Hi Nabhya,
Welcome to Microsoft Community.
I'm Hahn and I'm here to help you with your concern.
I understand that you are having difficulty updating your resume for the SDE Intern position. Unfortunately, in forum as a Microsoft agent, I do not have access to the Microsoft application portal.
However, I suggest that you reach out to the Microsoft recruitment team directly for assistance with updating your resume. You can find their contact information on the Microsoft Careers website. They will be able to guide you on how to update your resume within the application system or provide an alternative method for submitting the revised document.
I hope this helps, and I wish you the best of luck with your application!
Your Sincerely
Hahn - MSFT | Microsoft Community Support Specialist
