Most candidates prepare for interviews the wrong way. They spend weeks jumping between YouTube videos, documentation, LeetCode, and random interview questions. But they don't prepare efficiently. Interview preparation should be intentional.

Over the next 30 days, you'll progressively build the four pillars every interviewer evaluates:

• Technical Competence
• Problem Solving
• Communication
• Collaboration

The goal isn't to become a different engineer in 30 days. The goal is to become the best version of the engineer you already are.

Focus: Understand yourself before studying technology. This week is about identifying your strengths, weaknesses, and the areas that deserve your attention.

Your checklist

• Update your résumé.
• Review every technology listed on it.
• Remove anything you can't confidently discuss.
• Prepare your “Tell me about yourself” introduction.
• List your 5–8 strongest projects.
• For each project, write down:
  • The problem
  • Your role
  • Your solution
  • The impact
  • One lesson learned
• Research the companies you're targeting.
• Create a document where you'll collect interview notes throughout the month.

Daily habit

Spend 20–30 minutes explaining one technology from your résumé out loud. If you struggle to explain it simply, you don't understand it well enough yet.

Focus: Stop memorizing. Start understanding. Choose the technologies that appear most frequently on your résumé. For each one, answer these five questions:

• What problem does it solve?
• Why did we use it?
• What alternatives exist?
• What trade-offs does it introduce?
• When would I avoid using it?

Your checklist

• Review your primary programming language.
• Review databases.
• Review system architecture basics.
• Solve 1–2 coding problems every day.
• Explain every solution aloud.
• Review one real project every evening.

Daily habit

Don't finish a coding problem until you can explain:

• your approach,
• your complexity,
• your trade-offs,
• and one possible improvement.

Focus: Turn knowledge into interview performance. Many candidates know the answers. Few can communicate them under pressure. This week is all about practice.

Your checklist

• Complete at least 2 mock interviews.
• Answer 20 behavioral questions.
• Practice 3 system design problems.
• Solve coding problems using a timer.
• Record yourself answering technical questions.
• Review your recordings and improve your explanations.

Daily habit

Every day, answer three questions:

• One technical question.
• One behavioral question.
• One coding problem.

Focus: Build confidence—not new knowledge. At this stage, resist the temptation to learn another framework or read another book. Instead, reinforce everything you've already practiced.

Your checklist

• Review your project stories.
• Review your behavioral examples.
• Review your coding mistakes.
• Research every company you're interviewing with.
• Prepare thoughtful questions for the interviewer.
• Complete one final mock interview.

Daily habit

Spend the last 30 minutes of every study session reviewing what you've learned instead of learning something new.

Confidence comes from repetition.

Weekly scorecard

At the end of each week, ask yourself:

• Can I explain every technology on my résumé? ☐
• Can I solve problems while thinking aloud? ☐
• Can I explain my biggest projects clearly? ☐
• Do I have examples prepared for behavioral questions? ☐
• Am I improving every week? ☐

If you answered "no" to any of these questions, spend more time strengthening that area before moving on.

Two weeks isn't enough time to learn everything. But it's more than enough time to become interview ready.

At this stage, your goal isn't to master new technologies. Your goal is to strengthen what you already know, identify weak spots, and practice under realistic interview conditions.

Every study session should have a clear purpose. Focus on quality over quantity.

Focus: Reinforce your technical foundation and eliminate knowledge gaps. Review the technologies that appear on your résumé. Don't try to learn something completely new. Instead, deepen your understanding of the tools you've already used.

Your checklist

• Review every major technology on your résumé.
• Practice explaining each technology using the framework:
  • What problem does it solve?
  • Why did you choose it?
  • What alternatives exist?
  • What trade-offs does it introduce?
  • Where did you use it?
• Solve 2 coding problems every day.
• Practice one system design exercise.
• Prepare your “Tell me about yourself” introduction.
• Write down your 6–8 strongest behavioral stories.

Daily habit

Spend 30 minutes speaking out loud.

• Explain a technical concept.
• Answer one behavioral question.
• Walk through one coding solution.

Remember: interviews are conversations—not written exams.

Focus: Perform the way you'll be expected to perform on interview day. By now, you should spend less time studying and more time practicing. Treat every session like a real interview.

Your checklist

• Complete 2–3 mock interviews.
• Solve coding problems using a timer.
• Practice explaining one system design from start to finish.
• Research every company you're interviewing with.
• Prepare thoughtful questions to ask the interviewer.
• Review the mistakes you've made during practice.

Don't repeat them.

Daily habit

Every day, complete one interview simulation:

• One technical discussion.
• One coding problem.
• One behavioral question.

The more realistic your practice feels, the more comfortable you'll be during the real interview.

One week before your interview isn't the time to learn a new framework or solve hundreds of coding problems.

It's the time to sharpen your strengths, eliminate uncertainty, and build confidence.

Think of an athlete before a championship. They don't completely change their training plan the week before the competition. They refine what they've already practiced.

Your preparation should be no different.

Focus: Make sure you're confident discussing your own experience.

Your checklist

• Review your résumé line by line.
• Be ready to explain every technology you've listed.
• Review your 5–8 strongest projects.
• Practice your “Tell me about yourself” introduction.
• Identify any topics that still make you uncomfortable.

Goal

✔ Eliminate uncertainty before interview week begins.

Focus: Refresh your core technical knowledge.

Your checklist

• Review your primary programming language.
• Review the frameworks and tools you use most often.
• Revisit common design patterns and architectural concepts.
• Practice explaining technical concepts out loud.

Focus: Practice your problem-solving process.

Your checklist

• Solve 2–3 coding problems.
• Think out loud while solving.
• Explain your complexity analysis.
• Test every solution.
• Review mistakes instead of rushing to the next problem.

Focus: Practice the conversations that can't be memorized.

Your checklist

• Complete one full system design exercise.
