What you want is

chomp(my $input_name = <STDIN>);
push @EMP_INFO, $input_name;
[download]

Or perhaps you might want to abstract things ever so slightly:

sub Query {
  print "@_\n"; 
  chomp(my $ans = <STDIN>); 
  return $ans;
}

push @EMP_INFO, Query("What is your name?");
push @EMP_INFO, Query("What is the location?");
push @EMP_INFO, Query("What is the age?");

And your loop is very unperlish. A more perlish way to write it would be:

for my $ei (@EMP_INFO) { print "$ei\n"; }
[download]

Or maybe even

print map { "$_\n" } @EMP_INFO;
[download]

That's assuming that there's other things you want to do in the loop. If not, then just

print "@EMP_INFO";                   # or
print join "\n", @EMP_INFO;
[download]

May be enough

You could use Term::ReadKey too (something I always do). Sample:

use strict;
use Term::ReadKey;
use Data::Dumper;

my @EMP_INFO;

ReadMode('normal');
print "What is your name: ";
push @EMP_INFO, ReadLine(0);
print "What is the location name: ";
push @EMP_INFO, ReadLine(0);
print "What is the age: ";
push @EMP_INFO, ReadLine(0);

foreach (@EMP_INFO) {
  chomp;
  print $_ ."\n";
}

Please note that it's quite useles to chomp something and adding "\n" again, but this shows that if you are using this, and not directly printing the contents of @EMP_INFO, you may want to chomp the contents :)
