I generally have an idea of what the name will be like before I start writing. It's a little hard to explain.
Some examples:
I knew my protagonist in one story would have a "standard" name that started with J, was two to three syllables long, and could be shortened to a one syllable nickname that you don't see too often.
I used Jeremy as a placeholder for a while, with Jerm as the nickname, though I knew that wouldn't be the final name. It was "close enough" however. Without a working name like that I find it hard to write. Weeks later it "clicked" for me and I swapped to Jackson/Jacks.
Another story I wanted a girl named after a sound of some kind, preferably a once syllable name, based on a word that could have originally been used to make fun of her.
This one came quickly, and I settled on "Munch." After I had that I chose a "real" name of Margaret, which only one person calls her, and continued writing.
Yet another example is when you want a normal-sounding-name-that-is-not-normal. In that case I just take some normal, popular names (usually from a site like Nameberry), and mess around with letters until something hits.
Lom or Tam instead of Tom. Jeslen instead of Ellen. Jurry instead of Jerry. Meddy instead of Dotty, Zake/Jake, Mery/Mary, and so on.
Pick names and alter them so that the form is familiar but the letters aren't.
But yeah, I always have a "placeholder" name that is similar to the name I end up using. But that's just me and how I do it -- others are going to be different.
