About Senior Tech Prep
Senior Tech Prep was created to help software engineers understand technical interview topics more deeply, not just memorize answers.
While preparing for senior software engineering interviews, I discovered that many explanations online focused on definitions and buzzwords but skipped the most important part: why things work the way they do.
Understanding concepts such as concurrency, distributed systems, Kafka, JVM internals, caching, Spring Boot, and system design often requires intuition, diagrams, and practical examples. Many topics only truly clicked after spending time digging beneath the surface.
This website is an attempt to capture those explanations in a way that is easier to understand and easier to remember.
Rather than focusing on memorizing interview answers, the goal is to build a deeper understanding of the concepts behind them.
What You'll Find Here
- Java and concurrency fundamentals
- Spring Boot and backend development concepts
- System design explanations and tradeoffs
- Coding patterns used in technical interviews
- Visual diagrams and practical examples
- Real interview preparation notes and lessons learned
A Work In Progress
This site continues to grow as new topics are added and existing explanations are improved. If even a handful of engineers walk away understanding a difficult concept more clearly than before, then the project is accomplishing its goal.
