Preparing for a tech interview can be overwhelming—especially with the breadth and depth of topics you’re expected to master, from Data Structures & Algorithms (DSA) to System Design, Behavioral Interviews, and more. But with a focused 60-day plan, you can make meaningful progress and significantly boost your chances of landing that dream job.
This comprehensive guide will break down exactly how to structure your 60-day tech interview preparation, including daily and weekly goals, expert tips, and the best free (and paid) resources to help you succeed. Plus, we’ll show you how to integrate platforms like InterviewHelp.io and Preppal.InterviewHelp.io for a personalized edge in your preparation journey.
🧠 Why a 60-Day Plan?
A 60-day plan strikes the perfect balance between being long enough to build competency and short enough to maintain motivation. It works best for:
- Final-year students targeting placements.
- Working professionals aiming for career switches.
- Recent graduates preparing for off-campus opportunities.
This plan assumes that you can dedicate 2–4 hours daily on weekdays and 4–6 hours on weekends. If you have more time, you can fast-track the plan; if less, extend it to 90 days.
🗓️ The 60-Day Tech Interview Prep Framework
We’ll divide the 60 days into 4 key phases:
- Foundation (Days 1–15)
- Application (Days 16–30)
- Advanced Prep + Mock Interviews (Days 31–45)
- Polish & Perform (Days 46–60)
Let’s go through each phase in detail.
Phase 1: Foundation (Days 1–15)
