0.5 less because I really don't know if we missed anything important as Spring is so vast. And also, because I expect a better compiled PDF with the answers and it would be great if you could add a basic complete project and show a basic overview/flow of the project. Thanks, this was good for a quick revision!

By Deepa Sinha on 5/6/2026

It is a quick brush up for all the concepts but the person who is preparing for interview needs to structure the response including all these concepts. I feel structured response to all the questions( to be readily used in interview) is little missing but I really appreciate the content.

By Anitha Prasad on 9/23/2025

This course will certainly help for interview preparation. But I could see only slides from the github. I request Ranga Karanam, to provide explanation along with the slides, so that we can refer to and read it by ourselves instead of redoing the course everytime. It would be very very helpful. Thank you.

By POPA on 6/23/2025

He covered all main topics, really useful. I could say that the concepts are briefly explained, but they are good start to revise, pause and lear more about. The videos are short such that you do not feel overwhelmed.

By Luke DeRienzo on 5/9/2025

The Good: I'm pleased with the selection, succession, and pace of topics. The Less Good: I felt the explanations could have been much better laid out and explained besides just bouncing around back and forth between slides jiggling the cursor around.

By Andrian Soluk on 12/12/2021

The course was very useful. But I think the Spring Bean life cycle is one of the most important things to ask in an interview, but it hasn't been covered in this course. In addition, I think that the differences between Hibernate and JPA should be considered in more detail in this course

By Pavan Kumar Varanasi on 6/11/2021

Yes this course is good match for me. I am J2SE developer from seven years. I worked to consume REST etc API's throughout the career. From last six months I am focusing working towards back-end development. I completed 6 courses in 6 months from various sources. This is the seventh month were I want to cover the ground with a quick revision. This gave me enough confidence. I will try to answer the listed questions and practice. I am looking for an opportunity to work on spring boot and microservices. I had an experience in the past as an assistant professor for an year as well.

By Zaryab Saiyadain on 11/7/2020

Tutor is excellent and provides good basic knowledge on spring boot but we suppose to get some advanced interview question as well for spring boot. Part 2?
