Algorithms & Data Structures: Interview Practice Tests

Welcome to "Algorithms and Data Structures Interview Practice Tests" - a focused practice test-only course designed to help you master DSA through structured, exam-style questions. Whether you are preparing for coding interviews, university exams, or job placements, this course gives you a hands-on approach to solving problems using C++, Java, or Python. This course is not filled with tutorials or lectures.

It is a pure practice environment where you learn by solving real interview questions - the type asked in coding rounds and technical interviews across the industry. Why This Course Is EssentialIn most technical interviews today, especially in product-based and startup companies, knowledge of data structures and algorithms (DSA) is critical. Recruiters assess not just your coding skills but how you approach and solve algorithmic problems under time pressure.

This course helps you:Understand core DSA conceptsPractice C++ and Java coding questionsGet confident for your coding interviewsReinforce your theoretical understanding through hands-on solvingWho Should Take This CourseThis course is made for:Students preparing for campus placementsProfessionals preparing for technical interviewsLearners looking to build confidence in DSA using Java, C++, or PythonIndividuals preparing for companies that test with Java DSA or DSA C++ based questionsIt is also useful if you are enrolled in a full DSA course and want to test your understanding. Topics Covered in the Practice TestsYou will solve over 300 interview-style questions, sorted by topics and difficulty (Easy, Medium, Hard). Below is the full outline.

1. Time and Space ComplexityBig O, Big Theta, Big OmegaAnalyzing loops and recursive functionsTrade-offs between time and memory2. Arrays and StringsSearch, sort, rotate, subarraysSliding window and two-pointer problemsString reversal, pattern match, duplicates3.
