Most candidates spend 2-3 months preparing intensively. Focus on solving 150-200 LeetCode problems, with emphasis on medium and hard difficulties, and practice system design if applying for senior roles. Consistency is key; aim for daily practice sessions of 2-3 hours.

Priority topics include arrays, strings, linked lists, trees, graphs, and dynamic programming. Impact Analytics often tests problem-solving with real-world analytics scenarios, so practice problems involving data manipulation and optimization. Be comfortable with recursion and complexity analysis.

Avoid jumping into coding without fully understanding the problem; always ask clarifying questions. Also, don't neglect edge cases or fail to discuss your approach aloud. Impact Analytics values collaborative problem-solving, so engage the interviewer in your thought process.

Demonstrate knowledge of Impact Analytics' products and mention how your skills align with their mission. In behavioral rounds, use specific examples that highlight leadership and impact, referencing their core values. Show enthusiasm for data-driven decision making and scalability challenges.

You can expect feedback within 1-2 weeks after each round. The entire hiring process usually takes 4-6 weeks from initial screen to offer. If delays occur, follow up with your recruiter after the stated timeframe for updates.

SDE-1 interviews focus on core DSA and coding fundamentals with clear problem statements. SDE-2 roles include deeper system design questions and expect you to discuss trade-offs, scalability, and past project leadership. Prepare to design systems that handle large-scale data for SDE-2.

Use LeetCode and filter by company tags if available, but also practice general medium/hard problems. For system design, study case studies from books like 'Designing Data-Intensive Applications' and practice with peers on analytics-specific designs like recommendation systems or data warehouses.

Impact Analytics emphasizes values like customer obsession, innovation, and delivering results. They assess cultural fit through behavioral questions probing your adaptability, teamwork, and passion for data. Prepare stories that show you thrive in fast-paced, impact-oriented environments.
