Really great questions and liked the way the important keywords are focused and asked their real time use cases. 15:38 Final keyword real time usage and does it improve the performance of the application or degrades it ? Ans -> Use of final keyword is for compile time optimization - the compiler can optimize the code more effectively when it knows that a variable or method cannot be changed 16:20 Can you tell me about Polymorphism ? Can you tell me a scenario where Polymorphism solved the architecture level problem? Ans -> Polymorphism allows an architect to define an interface to behavior that is independent to how the behavior is implemented (Reporting System). 17:44 Can you explain HashMap and Hashset ? Internal working of HashMap and HashSet 21:06 Which Java version do you use currently? What new features are available in Java 8 now? 21:52 Why Java Stream APIs were introduced ? 23:42 Can you tell in brief about Hashcode and equals method? 25:12 Why don't we use primitive data types in Collection framework ? Ans -> Collections requires objects for manipulation and primitives are not derived from object 26:08 How do you secure the REST APIs in your application? 28:15 What algorithms are used in Arrays.sort() and Collections.sort() ? Ans -> Arrays.sort() used Dual Pivot Quick sort algo for primitive datatypes and Tim sort algo for Object types. Where as Collections.sort() used only Tim Sort ()Hybrid of Merge + Insertion Sort) algorithm internally. 29:21 Do you know about Webflux and mono in java application ? 29:51 Difference b/w Controller and RestController annotations? 31:05 What are the best practices while writing REST APIs? 33:06 Difference between Component, Service and Repository annotations? 35:48 Can you explain Spring Bean Lifecycle? 36:15 What are the uses of Response Entity? 37:00 What should be the Delete API method status code? Ans -> If Delete API is returning some response then status code should be 200, if no content is returned then 204 status code are considered good practice. 38:33 Have you handled anything related to Timeout error if API times out? What can you use in this case? 40:14 How does basic Authentication work in REST APIs? 41:07 How would you configure CORS policy in Spring Boot Application to accept Cross Origin request from front end? 42:20 How would you secure sensitive data in Spring Boot Application that is accessed by multiple users with different roles? 43:50 Are you familiar with any specific tools or practices for monitoring logs? 45:04 How do you manage dependencies in Maven project? 45:42 How would you revert changes in Git if you accidentally pushed a bug to the main branch? Ans-> git revert command can be used for that. 47:20 What is the purpose of Unit testing in Software Development Life Cycle? 48:19 Coding Problems

Sir one doubt about the interview as in interview they will ask mostly concept wise questions or problem solving questions please let me know Thank you

Unless the company is product based companies it'll be mostly conceptual based questions and problem solving questions could be used as a tie breaker or leveraged to ask higher CTC

This seems to be a little a easy questions for 5 year exp. it would be better if you include a bit more complicated or twisted questions.
