Congratulations on completing the "Data Structures for Coding Interviews in Java" course.
In this course, we worked through the data structures that appear most frequently in coding interviews, examined the patterns that make each one useful, and built the performance framework needed to apply that knowledge confidently in Java.
Here is a summary of what we covered along the way.
Algorithm Analysis introduces Big O notation, time and space complexity, and how to reason about trade-offs between data structures before writing any code.
Interview Readiness covers the process that turns knowledge into performance: the first five minutes framework, how to think out loud, how to verify solutions systematically, and what interviewers are actually evaluating beyond correctness.
Arrays examines how Java arrays work in memory, why index access is
