After my 100th interview, I got the offer. The previous 99? All lessons.

If you're currently in the grind of job hunting, I want you to know: I understand.

Two years ago, I started my job search journey. Back then, I naively thought finishing LeetCode would help me crush any interview. The result? I interviewed at 100 companies and got rejected 99 times.

Each rejection felt like a slap in the face. But those 99 failures taught me the true meaning of interviewing.

Today, I want to share these hard-earned lessons with you. I hope you can avoid my mistakes and land your dream job sooner.

Interviews 1-30: I Thought LeetCode Was Enough

My "Algorithm Dream"

Back then, I was a LeetCode devotee. I solved 5 problems every day for six months. I wore out my copy of "Cracking the Coding Interview" and memorized all the high-frequency problems.

I thought I was invincible.

First Reality Check

Then I interviewed at a well-known tech company.

Round 1 Algorithm: Two Sum. Nailed it.

Round 2 Algorithm: Binary Tree Level Order Traversal. Easy.

Confident, I advanced to round three. The interviewer asked:

"Can you explain the architecture of this project on your resume? Why did you choose this tech stack? What challenges did you face? How did you solve them?"

I froze.

I stammered through a response, but it was all surface-level. The interviewer followed up: "If your user base grew 10x, how would your system scale?"

I couldn't answer.

Result: Rejected.

Lesson #1

Algorithms are just the entry ticket. Project experience determines whether you stay.

Interviewers aren't testing if you can write code—they're testing if you can do the job.

Interviews 31-60: I Started Memorizing Answers

My "Standard Answer" Strategy

After a few rejections, I got "smart."

I started collecting "interview FAQs" and memorizing standard answers:

"What are your strengths?"
"What's the biggest challenge you've faced?"
"Why do you want to join our company?"

I even prepared a 30-page interview notebook with "perfect answers" for every question.

Second Reality Check

I interviewed at a startup.

The interviewer asked: "What's the biggest challenge you've faced?"

I confidently recited my prepared answer:

"In my previous project, I encountered a performance bottleneck. After analyzing logs, I found slow database queries. I optimized indexes, introduced caching, and reduced response time from 3 seconds to 200 milliseconds..."

The interviewer interrupted: "Wait, you said you analyzed logs. What tools did you use? What did the logs show?"

I froze.

Because I made it up.

I had never actually done this project. It was just a "standard answer" I copied from the internet.

The interviewer continued: "What caching did you use? Redis or Memcached? Why that choice? How do you handle cache stampede?"

I panicked and started making things up.

Result: Rejected again.

Lesson #2

Memorized answers can't withstand follow-up questions. Interviewers ask about YOUR real experiences, not answers you memorized.

Authenticity matters more than perfection.

Interviews 61-90: I Learned to Tell Stories

My "STAR Method" Era

After dozens more failures, I discovered the STAR method:

S (Situation): The context
T (Task): What needed to be done
A (Action): What you did
R (Result): The outcome

I thought I found the answer.

I reorganized my project experiences using STAR, giving each story a clear beginning and end.

Third Reality Check

I interviewed at a multinational company.

The interviewer asked: "Tell me about your most fulfilling project."

I began my STAR performance:

"S: Our team needed to develop a user growth system. T: I was responsible for designing and implementing the core recommendation algorithm. A: I researched various algorithms, chose collaborative filtering, and built a real-time computation framework. R: After launch, user retention increased by 30%."

The interviewer was silent for a few seconds, then said:

"Sounds perfect. But I have a question: Did you make any mistakes during this process?"

I froze.

My STAR story had no mistakes—only success.

The interviewer continued: "I want to see the real you, not the perfect you. Everyone makes mistakes. What matters is how you learn from them."

Result: Rejected again.

Lesson #3

The STAR method is great, but if your story is too perfect, it feels fake.

Interviewers want to see a real person—someone who makes mistakes, reflects, and grows.

Interviews 91-100: I Finally Got It

My Epiphany Moment

After my 91st rejection, I broke down.

I sat in a coffee shop, watching people pass by, and asked myself: What am I doing?

Suddenly, I realized: I had been performing.

I was performing as a "perfect candidate," an "error-free programmer," a "standard answer machine."

But I forgot the most important thing: Interviewers aren't testing me—they're trying to understand me.

They're looking for someone they can work with, not a testing machine.

The 100th Interview

With this new understanding, I walked into my 100th interview.

This time, I didn't memorize answers or perform perfection.

The interviewer asked: "What's your biggest failure?"

I took a deep breath and said:

"Honestly, my biggest failure is these 99 interviews. Every rejection made me feel I wasn't good enough. But now I understand—those failures taught me the most important lesson: be your authentic self."

The interviewer smiled and said: "That's the most genuine answer I've heard."

Result: I got the offer.

The Most Important Lesson

An interview isn't an exam—it's a conversation.

Interviewers aren't your enemies; they're your potential colleagues. They want to see the real you, not the perfect you.

5 Hard-Earned Lessons

Lesson 1: Project Experience Matters More Than LeetCode

Failure Case: I spent six months on LeetCode but couldn't answer project questions.

Lesson: Algorithms are just the threshold. Project experience is the real competitive advantage. Interviewers want to know: Can you solve real problems?

Advice: Split your LeetCode time in half. Use the other half to dive deep into your projects. Understand every technical decision, every problem, every solution.

Lesson 2: Understanding Beats Memorization

Failure Case: I memorized 30 pages of standard answers and got exposed by follow-up questions.

Lesson: Interviewers don't ask what you memorized—they ask what you understand. Rote memorization will crumble under questioning.

Advice: Don't memorize answers—understand principles. If you truly understand, you can answer any follow-up question.

Lesson 3: Authenticity Beats Perfection

Failure Case: My STAR story was too perfect, which made it feel fake.

Lesson: No one is perfect. Interviewers want to see the real you—including your mistakes and growth.

Advice: Share your failures and what you learned from them. This is more persuasive than a perfect success story.

Lesson 4: Questions Matter More Than Answers

Failure Case: When interviewers asked if I had questions, I always said "no."

Lesson: Asking questions is your chance to show critical thinking and learn if the company is right for you.

Advice: Prepare 3-5 thoughtful questions. For example:

"What's the biggest technical challenge your team is facing?"
"If I join, what are the expectations for the first three months?"
"Can you share a recent technical problem your team solved?"

Lesson 5: Mindset Beats Techniques

Failure Case: I was so focused on performing well that I came across as nervous and unnatural.

Lesson: Interviews are two-way streets. You're evaluating the company as much as they're evaluating you. Stay calm and be yourself.

Advice: Treat interviews as technical conversations. You're not taking an exam—you're chatting with future colleagues.

If I Could Start Over

If I could go back two years, here's what I would do:

Less LeetCode, More Projects

I'd limit LeetCode to one hour daily and spend the rest on real projects. One deep project is worth 100 LeetCode problems.

Document Growth, Not Memorize Answers

I'd create a "growth journal" recording every problem I faced, every solution I tried, every failure and reflection. These real experiences are the best interview material.

Mock Interviews, Not Solo Prep

I'd find friends or mentors for mock interviews and get honest feedback. Solo preparation can never reveal blind spots.

Research Companies, Not Interview Questions

Before each interview, I'd deeply research the target company: their products, tech stack, team culture. Only then could I ask meaningful questions and show genuine interest.

Stay Calm, Don't Obsess

I'd tell myself: Rejection isn't failure—it's filtering. Companies that reject you are actually saving your time.

FAQ

Q1: I've solved many problems but still can't pass interviews. What should I do?

A: LeetCode is just the foundation. Focus on project experience. Deeply understand the projects you've worked on—why you made certain choices, what problems you faced, how you solved them. Algorithms get you in the door; project experience keeps you there.

Q2: I don't have big company experience and my projects are ordinary. How should I prepare?

A: Ordinary projects are fine—what matters is your depth of understanding. Even a simple CRUD project can be explored deeply: Why this design? What could be optimized? How would it scale 10x? Depth beats breadth.

Q3: I get too nervous during interviews and my mind goes blank. Help?

A: Nervousness is normal. Some tips:

Take deep breaths before the interview. Tell yourself "this is just a chat."
Bring a notebook with key points. Look at it if you get nervous.
If you're stuck, say "Can I have a minute to think?" Interviewers understand.

Q4: What if I don't know the answer to a question?

A: Don't panic. Honestly say "I haven't explored that in depth," then try to share your thinking process. Interviewers care more about how you think than whether you know the answer.

Q5: How do I know if a company is worth joining?

A: Interviews are two-way. Ask yourself:

Was the interviewer professional?
Were the questions reasonable?
Is the tech stack interesting to you?
Did the team vibe feel right?

If something feels off during the interview, it might not be the right place for you.

Final Thoughts

100 interviews, 99 rejections. Sounds brutal, but I'm grateful for those 99 failures.

They taught me:

Technical skills matter, but communication matters equally
Preparation matters, but authenticity matters more
Techniques matter, but mindset matters most

If you're struggling in your job search right now, I want to tell you:

Don't give up. Every failure brings you one step closer to success.

An interview isn't the destination—it's the beginning. Getting the job is just the first step. What matters more is finding the right place to do work you love.

You've got this.
