Frequently Asked Questions
Everything you need to know about Technical Interview Prep
How many problems should I solve before interviewing?
We recommend solving 150-200 problems across different categories and difficulty levels. Focus on understanding patterns rather than memorizing solutions. Our platform tracks your progress and suggests when you’re ready for interviews.
Do I need to know system design for junior roles?
For entry-level positions, basic system design knowledge is helpful but not always required. However, understanding fundamental concepts like databases, APIs, and scalability will set you apart. We offer beginner-friendly system design content.
Which programming language should I use for interviews?
Choose the language you’re most comfortable with. Python and Java are popular choices due to their readability and extensive libraries. Our platform supports all major languages with language-specific optimizations and best practices.
How do I prepare for system design interviews?
Start with fundamental concepts like scalability, reliability, and consistency. Practice designing common systems like URL shorteners, chat applications, and social media feeds. Our system design course includes hands-on exercises and expert feedback.
What if I get stuck during a coding interview?
Stay calm and think out loud. Start with a brute force solution, then optimize. Ask clarifying questions and discuss trade-offs. Our mock interviews teach you how to handle pressure and communicate effectively when stuck.
How long does it take to prepare for technical interviews?
Preparation time varies based on your background. New graduates typically need 3-6 months, while experienced engineers might need 6-12 weeks. Our personalized learning paths adapt to your skill level and target timeline.
