The interviewer said it was exactly what they were looking for.

function reverse(sentence){
	return sentence.split(" ").reverse().join(" ");
}

// in C#
public string ReverseWords(string s)
{
return string.Join(" ", s.Split(' ').Reverse<string>());
}

public class WordReverse {
    
    public static String reverseWords(String startString){
        String endString = "";
        String[] startArray = startString.split(" ");
        for (int i = startArray.length - 1; i >= 0; i--){
            endString += startArray[i];
            if (i != 0){
                endString += " ";
            }
        }
        
        return endString;
    }
    
    public static void main(String[] args){
        String s = "these are words that will be reversed";
        System.out.println(s);
        System.out.println(reverseWords(s));
    }
}

var s="these are words that will be reversed";
String.prototype.reverse = function() {
return this.split('').reverse().join('');
}
s.split(' ').map(function(w){return w.reverse()});

Another way without reverse():

function reverse(sentence) {
    var words = sentence.split(" ");
    while(words.length) {
        console.log(words.pop());
    }
}

reverse("hello world i am a robot");

function reverseWords(sentence){
var strArray = sentence.split(" ");
for(i=0; i<strArray.length; i++){
strArray[i] = strArray[i].split("").reverse().join("");
}
return strArray.join(" ");
}

Here is the answer in Ruby:

require 'pry'

def reverse_sentence(sentence)
sent_arr = sentence.split(' ')
reversed = []
sent_arr.each do |word|
reversed.unshift(word)
end
reversed.join(' ')
end


print reverse_sentence('Hi how are you? Hi how are you? Hi how are you? Hi how are you?')

JS solution:

function reverseSentence(str){
	return str.split(" ").reverse().join().replace(/,/g, " ");
}


var someSentence = "Create a function that will reverse the words in a sentence";
var newOrder = reverseSentence(someSentence);
console.log(newOrder);

function reverse(sentence) {
var words = sentence.split(" ");
var temp="";
var i=1;
while(words.length){
temp = temp+" "+words.shift().split("").reverse().join("");
}
console.log(temp)
}

reverse("hello world i am a robot");

function reverse(sentence) {
    var words = sentence.split(" ");
    var temp="";
    var i=1;
    while(words.length){
          temp = temp+" "+words.shift().split("").reverse().join("");
    }
    console.log(temp)
}

reverse("hello world i am a robot");

public string Reverse(string str)
{
	if(str.Length == 1)
		return str;
		
	return str[str.Length - 1] + Reverse(str.Substring(0,str.Length - 1));
}
