I would propose the following solution:

public static String makeNumeronym(String s) {
	if (s == null || s.length() < 3) 	return s;
	int N = s.length();
	return s.charAt(0) + (N-2) + s.charAt(N-1) + "";
}

Btw, isn it that marcus -> m4s? Is it something the interviewer expected?

module.exports = function (s) {
	var r = /^(.)(.{3,})(.)$/.exec(s);
	if (r) {
		r = r[1] + r[2].length + r[3];
	}
	return r || s;
};

That's certainly a warm up. Python lets you answer this essentially in one line:

def makeNumeronym(word):
    return (word[0] + str(len(word[1:-1])) + word[-1]) if (isinstance(word, str) and len(word) >= 3) else word

This would be even shorter if it didn't do type checking and length checking.

```ruby
{{string.size > 2 ? string[0] + (string.size - 2).to_s + string[-1] : string}}
```

{{s.size > 2 ? s[0] + (s.size - 2).to_s + s[-1] : s}}

public static String getNumeronym(String str){
    if(str == null){
        return null;
    }
    if(str.length() < 3){
        return str;
    }
    int length = str.length();
    return str.charAt(0) + Integer.toString(length - 2) + str.charAt(length -1);
}

public class Main {

public static void main(String[] args) {

String s = "house";
String expected = makeNumeronym(s);

System.out.println(expected);

}

private static String makeNumeronym(String s) {

int x = s.length() -1;
String y = s.substring(1, x);
int z = y.length();
String Numeronym = s.charAt(0) + String.valueOf(z) + s.charAt(x);

return Numeronym;

}
}
