This will fail at eof as then file.gets will return nil.  The strip 
should be put into the loop.

You can also heavily refactor:

file = File.new("test.txt", "r")
while (line = file.gets)
  line.strip!
  if line.empty?
    puts "-----"
  else
    @array = line.split(':')
    if m = @array[0].match(/(title|company)/)
      print "   #{m[1].capitalize}: "
    end
    puts "#{@array[1]}"
  end
end
file.close

Also, since your input seems to have spaces after the colons, you may 
want to ignore those.  If so, replace the split with:

    @array = line.split(/\s*:\s*/)
