March 17 has always been special to me. It is my birthday, a day that reminds me of growth, lessons, and looking forward. This year I decided to share one story that shaped me as a developer and left me humbled in ways I did not expect.

A few months ago, I was in a technical interview. Everything was flowing smoothly until the interviewer asked me to solve a simple challenge:

“Write a function that reverses a string. If the string is a palindrome, return false instead of the reversed string.”

At that moment, I froze.

I understood how to reverse a string, but I did not know what a palindrome was. The silence felt longer than it should have been. I could see the interviewer waiting patiently, and I felt my confidence slowly slipping away.

What is a palindrome?

For those who might not know, a palindrome is a word that reads the same backward as it does forward. Examples include words like level, radar, civic, or even short phrases like madam. So the challenge was not just about reversing strings. It was about understanding that extra condition where a palindrome should trigger a different output.

My struggle in that interview

The first challenge was ignorance. I had never encountered the term palindrome before that day. Not knowing the definition made me fumble around with guesses instead of thinking clearly.

The second challenge was pressure. Interviews have a way of magnifying small gaps in knowledge into towering roadblocks. My brain focused so much on the part I did not understand that I forgot the parts I already knew well.

The third challenge was problem solving under constraints. I was overthinking the problem instead of breaking it down step by step. Looking back, the logic was simple, but in the heat of the moment, it felt like rocket science.

How I eventually solved it

After the interview, I went back to my notes determined not to let this experience define me negatively. I researched what a palindrome was, wrote down examples, and then attacked the problem logically.

1. Step one was to reverse the string. In JavaScript, this meant splitting the string into an array, reversing it, and joining it back.

2. Step two was to check if the reversed string matched the original string. If it did, that meant it was a palindrome.

3. Step three was to return false if the word was a palindrome, otherwise return the reversed string.

Here is a simple version of the solution in JavaScript: Using Built-in Functions (Simple & Clean)

JavaScript

function reverseOrFalse(str) {
  const reversed = str.split('').reverse().join('');
  if (str === reversed) {
    return false;
  }
  return reversed;
}

console.log(reverseOrFalse("level")); // false
console.log(reverseOrFalse("adams")); // smada

Method 2: Using a For Loop (Manual Reversal)

JavaScript

function reverseOrFalse(str) {
  const reversed = str.split('').reverse().join('');
  if (str === reversed) {
    return false;
  }
  return reversed;
}

console.log(reverseOrFalse("level")); // false
console.log(reverseOrFalse("adams")); // smada

Method 3: Using Recursion (Elegant, but less common)

JavaScript

function reverseOrFalse(str) {
  function reverse(s) {
    if (s === "") return "";
    return reverse(s.substr(1)) + s[0];
  }

  const reversed = reverse(str);
  return str === reversed ? false : reversed;
}

console.log(reverseOrFalse("civic")); // false
console.log(reverseOrFalse("adams")); // smada

Method 4: Using Array reduce()

Functional programming style.

function reverseOrFalse(str) {
  const reversed = str.split('').reduce((rev, char) => char + rev, '');
  return str === reversed ? false : reversed;
}

console.log(reverseOrFalse("madam")); // false
console.log(reverseOrFalse("adams")); // smada

Method 5: Using ES6 Spread Operator + Reverse

A shorter, modern syntax.

function reverseOrFalse(str) {
  const reversed = [...str].reverse().join('');
  return str === reversed ? false : reversed;
}

console.log(reverseOrFalse("noon")); // false
console.log(reverseOrFalse("adams")); // smada

Method 6: Using Two-Pointer Technique (Efficient Check Without Reversing)

This one is smart: you don’t even reverse fully if you just want to check palindrome first.

function reverseOrFalse(str) {
  let left = 0, right = str.length - 1;
  let isPalindrome = true;

  while (left < right) {
    if (str[left] !== str[right]) {
      isPalindrome = false;
      break;
    }
    left++;
    right--;
  }

  if (isPalindrome) return false;

  // If not palindrome, reverse normally
  return str.split('').reverse().join('');
}

console.log(reverseOrFalse("level")); // false
console.log(reverseOrFalse("adams")); // smada

The lesson I took from this

That interview taught me something far more important than solving an algorithm. It reminded me that knowledge gaps are normal, but how you respond to them defines your growth.

I learned to:

• Stay calm when I encounter terms or concepts I do not know.

• Focus on breaking problems down instead of letting pressure take over.

• Embrace mistakes as teachers.

The funny thing is, now whenever I see a palindrome, I smile. It no longer feels like a scary term, but like an old friend that once humbled me and pushed me to improve.

Why I am sharing this on my birthday

Birthdays are about growth, reflection, and honesty. As I turn a year older today, March 17, I want this story to mark a shift. I am not just sharing wins but also the moments where I fell short, because those moments carry the deepest lessons.

To every developer reading this: if you have ever felt embarrassed in an interview or stuck on a simple problem, you are not alone. Those moments do not define you. What defines you is the persistence to come back, learn, and rise again.

And if you ever forget what a palindrome is, just remember me — the developer who once froze in an interview but came back stronger.
