About this app
Backend Interview Pro helps you prepare for Java backend developer interviews with short daily flashcard sessions. It covers the questions backend roles tend to focus on, from core Java and collections to Spring Boot and SQL, and it works offline with no account.
Study 100 interview questions across four topics:
CORE JAVA
equals() and hashCode(), immutable classes, generics and type erasure, streams, Optional, records, sealed classes, BigDecimal and memory basics.
JAVA COLLECTIONS
How HashMap works, ArrayList vs LinkedList, ConcurrentHashMap, TreeMap, PriorityQueue, immutable lists, time complexity and building an LRU cache.
SPRING BOOT
Dependency injection, bean lifecycle, auto-configuration, @Transactional, AOP proxies, exception handling, validation, testing, caching and Actuator.
SQL AND DATABASES
Joins, indexes, window functions, transaction isolation, optimistic and pessimistic locking, deadlocks, pagination, normalization and query tuning.
A STUDY PLAN FOR YOUR INTERVIEW DATE
Choose your experience level and when your interview is. The app sets how many new cards you see each day, so a one-week deadline gets a faster pace than an open-ended plan.
FLASHCARDS WITH SPACED REPETITION
Say your answer out loud, flip the card, then rate how well you remembered it. Cards you find hard come back sooner and cards you know well wait longer, so your time goes where it helps most.
ANSWERS WRITTEN FOR INTERVIEWS
Each question has a short answer you can say out loud, and many include a code example and a deeper explanation. Likely follow-up questions help you prepare for what an interviewer may ask next.
PRACTICE WITH AI
Copy a ready-made mock interview prompt for any question and paste it into the AI assistant you already use. It asks you the question, scores your answer and follows up.
TRACK YOUR PROGRESS
See your daily streak, total reviews and mastery for each topic. Bookmark questions, add any question to your review and search the whole question bank.
BUILT FOR PRIVACY
The app works offline, with no account and no ads. Your progress stays on your device, and the app does not collect your data.
COMING LATER: PRO
Pro topics are planned for concurrency, JVM internals, Spring Security, JPA and Hibernate, and microservices. Pro is not on sale yet. You can join the waitlist in the app, and there is no payment now.
