Inserting text of arbitrary length before rectangular region

[Gerard Lally]

I'm having difficulty understanding rectangular regions.

Let's say I want to enter the text "Name of applicant: " at the
beginning of each line below:

John
Henry
Mike
Tom

Positioning the cursor at the first character on line 1, I create a
rectangular region with 3q3jq

I then do c^S and at the prompt I enter "Name of applicant: " (without
quotation marks), but only the first letter N is entered.

Have I misunderstood what should happen here?

Thank you.
