Last year, When I had about 2,000 sq.ft. of real hardwood flooring put in, the crew had to deal with a hard concrete floor on the lower (bedroom) level and wood joist flooring on levels 2 and 3, the crew chief brought in about a 10 foot straight edge and chalked out low and high areas,that needed to be adjusted. His 100% minimally English speaking crew (Hispanic) used rubber mallets and beat the crap out of the hard wood flooring to get it perfect.
