1. Core java (60%), spring (15%), and databases (15%).
2. Data structure (HashMap, treemap, arraylist, linklist),
3. Streaming concepts (partitioning), Junit
4. Exception handling and workflow, Test coverage (why its important, how it gets handled at
java and spring layer, morckito library if the candidate knows that would be great),
5. OOPS concepts (inheritance),
6. Threading (mutex, threadpool, threading implementation, singleton factory, builder pattern,
abstract)
7. Real world problems (atleast 1 to be asked in IAAS interview) (movie ticket booking, parking
booking), To be asked to only selected candidates: Puzzle (probability/)
8. Memory management: Garbage Collection (GC), Heap dump, Thread dump, apache, google
library.
9. Spring frameworks and database. Data lakes, star lakes, schemas, indexing, partitioning,
optimize query, hibernate.
10. Data warehouse vs nosql vs time series database (KDB, DB2), data storage patterns.
11. Types of transaction control. Column level.
12. Query formation, grouping, nested queries, joints (inner joints, outer joints)
13. If candidate has spring exp: Architecture and various layers of Spring, coupling concepts,
dependency injections, inheritance, Bean level, JMS connection pooling concepts, Lambda,
Annotation vs XML, Kafka, Hibernates.
14. Good to have AI/ML inclination.
