Depends on age.
Older stairs were built on site with hammer and nails.
Later screws were used.

Mine where made in 2007 and machined so lock together with glue and wood blocks.
No screws or nails

A staircase is made up from these three main components.

Stringer.
Tread.
Riser.

Nothing fancy about how it's installed. The stringers are held by the wall(s) and supported by a joist or a course of couple bricks from below.
