The Spring Framework Interview Playbook: 30 Questions That Land You the Job
30 battle-tested questions with answers that hiring managers want to hear
Hello folks, if you are working in the Java world, then you must have heard about Spring Framework and Spring Boot. Spring Framework is very popular in the Java world for doing application development.
It provides dependency injection and inversion of control, and also provides several API like JdbcTemplate, JmsTemplate, RestTemplate, and WebClient to make developers’ work easier while working with JDK core libraries.
Since Spring is very important in the application development world, it’s also quite popular among interviewers. You will see a lot of questions from the Spring framework in both Java and JEE interviews.
It’s even more important in the web and enterprise development world due to the Spring MVC framework, but we will see it later.
Last week, I shared 35 Java Interview Questions and System Design Problems, and in this post, I am going to share with you some of the frequently asked Spring Framework questions from Java interviews.
These are from my own experience, given I have attended so many interviews in the last 7 years of my career :).
I am not providing answers for these questions because they’re mostly for preparation purposes. If I do, then when I use it to refresh my knowledge, I won’t be able to use it as a practice test.
Hopefully, I will write another post answering Spring questions from this article.
