Well, there's always more than one way to do anything,
but here's one late night hack :)

#!/usr/bin/env ruby

class ResumeBuilder
  def initialize
    @data = {}
    @fields = ['First Name',
               'Last Name' ,
               'Address'   ,
               'City'      ,
               'State'     ,
               'Zip'       ]
  end

  def prompt
    @fields.each do |field|
      val = @data[field]
      print "Please enter your #{field}#{(' (' + val + ')') if val}:"
      val = gets.chomp
      @data[field] = val if val != ''
    end
  end

  def confirm?
    puts "You entered:"
    @fields.each do |field|
      puts field + ': ' + @data[field].to_s
    end
    print "Is this correct? (Y/n)"
    gets.chomp == 'Y'
  end
end

resume = ResumeBuilder.new
resume.prompt
resume.prompt until resume.confirm?

I didn't bother with the formatting, but you get the idea.
You might also look at using a Struct.
