My daughter intentionally went old school with job applications.
Sent paper letter, on bond (personalized with in signature) , with resume on bond, and college transcript straight to the design makers, bypassing the HR.
Offered 5/5 jobs, took one.
Each said it was a delight to see an old school application.
Congrats to your daughter on her successful old-school efforts. She was fortunate the efforts landed at companies that have not drilled the HR shuffle into the management staff to ensure candidates get the same poor treatment. This usually means the hiring manager has no power and will be ignored by HR.
