Before I will baptize a person, I seek a credible profession of faith, meaning a profession of faith that demonstrates a basic and clear understanding of the Gospel and how that has impacted the person's life. For example, I will want to see that they understand that salvation is by grace through faith alone in Christ's finished work on their behalf, that they have come to know that their sins are forgiven, and that they desire to follow Christ in obedience (the latter of which is typically seen in their wanting to be baptized in the first place).
As a part of my talk with them, I also try to give them a basic teaching on the meaning and importance of baptism, although I know that they will grow in their understanding of this more and more in the days and years to come.
Just want to point out that paedobaptists are also credobaptists, meaning that we baptize people from outside the covenant community upon their profession of faith. So, there's really no place for the answer "infant baptism." We have to think through all the same things Baptists do when it comes to persons of age and voluntary consent.
