The "general rule" is 3-4 Inches of soil cover for new rhisomes and a covering of compost/manure every fall which will deepen that. Typical practice is to set the rhisome on the soil surface and mound soil over the top to create a hill.
Hops at their most vigourous grow a full foot a day (mostly because they continue to grow at night). If you mark your lines with a sharpie and come back a few hours later you'll see for yourself.
Bine growth should be no less vigorous for the variety the first year than the second or third, IF the plant is healthy and likes the area you've given it.
Don't expect much, if any, cones the first year. Although some will surprise you.
The underground growth is almost as vigorous as the above soil growth so be sure to give them some room and if possible limit how far they spread with some barriers underground. A term called boxing in. Raised beds are ideal for this but not the only way. Edging will do little more than keep the grass out (but doesn't do even that well).
