Land your dream tech job with a structured, end-to-end interview preparation programme covering coding challenges, system design, and behavioural interviews. Technical interviews are learnable skills — and this course gives you a proven system. Over 12 weeks you will sharpen your coding pattern recognition, develop a clear problem-solving framework, understand system design fundamentals, and walk into every interview with the confidence that comes from genuine preparation. What this course covers: → The most common coding interview patterns (not just random LeetCode grinding) → A repeatable framework for thinking through problems out loud → System design basics: how to design scalable, real-world systems → Behavioural interview mastery using the STAR method → Live mock interviews with actionable feedback → Resume, LinkedIn, and offer negotiation guidance Whether you are a student preparing for your first role or an engineer targeting a senior position at a top company, this course gives you the tools and practice needed to perform consistently under pressure.
Who this course is for
- Final-year students and recent graduates preparing for their first software engineering job
- Working professionals who want to switch to a top product-based company or FAANG
- Self-taught developers who feel confident coding but freeze up in structured interviews
- Anyone who has failed technical rounds and wants a systematic approach to improve
- Engineers targeting senior or staff roles that require stronger algorithmic and system design skills
- Candidates who want mock interview practice and personalised feedback before the real thing
What you’ll learn
- Approach coding problems using a clear, repeatable framework that interviewers respond to positively
- Recognise and apply the most common interview patterns: two pointers, sliding window, BFS/DFS, dynamic programming, and more
- Optimise solutions from brute force to efficient implementations within time and space constraints
- Explain your reasoning clearly and concisely while coding under pressure
- Solve medium-difficulty LeetCode problems consistently within 20–30 minutes
- Design scalable systems at a high level, covering key components such as load balancers, databases, caches, and message queues
- Structure compelling answers to behavioural questions using the STAR method
- Build a strong technical resume and LinkedIn profile that gets past initial screening
- Negotiate job offers with confidence using data-driven tactics
- Leave with a sustainable daily practice routine that maintains and improves your skills after the course

FAQs
Do I need strong DSA skills before joining?
A basic understanding of common data structures (arrays, maps, trees) is helpful. If you want to build that foundation first, our Data Structures & Algorithms course is a great prerequisite.
Which programming language should I use?
You can use any language you are comfortable with. Python is the most commonly used in sessions, but Java, C++, and JavaScript are all supported.
How is this different from just practising on LeetCode?
This course gives you structure, patterns, and a problem-solving framework. Instead of grinding randomly, you learn to recognise problem types and apply proven approaches consistently.
Will the mock interviews be with real people?
Yes. Mock interview sessions involve peer practice and instructor-led rounds with feedback on your communication, approach, and solution quality.
How many coding problems will I solve?
Approximately 75 curated problems across Weeks 1–8, selected to cover the highest-frequency interview patterns.
Is system design covered in depth?
Week 9 covers the fundamentals needed for most interviews at mid-level and above. For very senior roles, additional self-study is recommended.
Will I receive a certificate?
Yes, a certificate of completion is awarded upon finishing the full 12-week programme.
