Not sure where to start? Your experience level determines which roles and question types to prioritize first.
Junior (0-2 Years)
Start here: Software Engineer or Project Manager
At the junior level, interviewers focus on fundamentals. For engineering roles, that means data structures, basic algorithms, and clean code. For project management, it means understanding core methodologies and demonstrating organized thinking. Behavioral questions will center on teamwork, learning from mistakes, and communication skills.
Preparation tip: Spend 60% of your time on technical fundamentals and 40% on behavioral stories. You need fewer stories at this level, but each one should be specific and well-structured.
Mid-Level (3-6 Years)
Start here: Software Engineer, Product Manager, or Data Scientist
Mid-level interviews expect you to demonstrate ownership and independent judgment. Technical questions get harder, and you will face system design or product design rounds. Interviewers want to see that you can scope problems, make trade-off decisions, and mentor others. Your behavioral answers should show increasing responsibility and impact.
Preparation tip: Balance technical depth with leadership stories. Practice explaining your reasoning process out loud, not just arriving at correct answers.
Senior / Staff (7+ Years)
Start here: System Design, Product Manager, or your target role guide
Senior interviews prioritize architecture, strategy, and cross-team influence. Technical questions focus on scale, reliability, and long-term maintainability. Behavioral rounds assess how you drive alignment across teams, handle ambiguity, and make high-stakes decisions. Expect deeper follow-up questions that test the boundaries of your experience.
Preparation tip: Prepare 8-10 detailed stories that demonstrate strategic thinking, mentorship, and organizational impact. For system design, practice talking through trade-offs for 45+ minutes on a single problem.
How to Use These Guides
Identify Your Target Role
Pick the role guide that matches the job you are interviewing for. If you are switching careers, start with the new role guide and supplement with your strongest transferable skills. Each guide is designed for a specific interview format, so the right starting point saves you hours of unfocused preparation.
Review the Interview Format
Every role has a different interview structure. Product Managers face product design cases. Software Engineers solve live coding problems. Data Scientists interpret datasets. Understanding the format before you start practicing ensures you allocate time to the rounds that matter most for your target role.
Practice the Core Questions
Work through the role-specific questions in your guide. Do not just read the answers. Say your responses out loud and time yourself. For technical questions, solve them on paper or a whiteboard before checking solutions. For behavioral questions, use the STAR method to structure every answer around a real experience.
Simulate with AI Mock Interviews
Reading and solo practice only take you so far. The real gap is performing under pressure with follow-up questions, time constraints, and an evaluator watching.

Generic interview advice wastes your time. A Software Engineer who only prepares behavioral answers will struggle in coding rounds. A Product Manager who drills algorithms instead of product cases will underperform in design discussions. The interview format is different for every role, and your preparation should match.
Role-specific preparation gives you three advantages:
- Focus: You study only what your interviewers will actually ask, instead of spreading thin across irrelevant topics.
- Confidence: When you know the format in advance, you spend less mental energy on surprises and more on delivering strong answers.
- Speed: Targeted practice builds the specific skills each role tests, so you improve faster than someone following a generic study plan.
Every role guide on this page follows the same structure: interview format overview, common questions with example answers, preparation strategies, and a practice plan you can start today.
Cross-Role Skills That Transfer
While each role has unique technical requirements, several skills show up in every interview process. Strengthening these gives you an advantage regardless of your target position.
- Structured communication: Every role rewards candidates who organize their thoughts before speaking. Use frameworks like STAR for behavioral answers and clear step-by-step reasoning for technical questions.
- Stakeholder awareness: Whether you are a Software Engineer explaining a technical decision or a Product Manager presenting a roadmap, showing that you consider different perspectives earns trust with interviewers.
- Problem decomposition: Breaking complex problems into manageable parts is valued in coding rounds, system design, product cases, and data analysis alike.
- Self-awareness: Knowing your strengths and growth areas, and being honest about them, signals maturity across every role.
Practice these cross-role skills with realistic mock interviews that give you feedback on how you communicate, not just what you say.
