Microservices Interview Questions Preparation Course

Microservices Architecture is one of the fastest growing software in technology world. Big companies like Amazon, Netflix, Google etc use Microservices based architecture. This course is designed to help you achieve your goals in Microservices field. Software Engineers with Microservices knowledge may get more salary than others with similar qualifications without Microservices knowledge.

In this course, you will learn how to handle interview questions on Microservices technology in Software Design and Development. I will explain you the important concepts of Microservices architecture.

You will also learn the benefits and use cases of Microservices in this course. 

What is the biggest benefit of this course to me?

Finally, the biggest benefit of this course is that you will be able to demand higher salary in your next job interview.

It is good to learn Microservices for theoretical benefits. But if you do not know how to handle interview questions on Microservices, you can not convert your Microservices knowledge into higher salary.

What are the topics covered in this course?

We cover a wide range of topics in this course. We have questions on Microservices best practices, Security, Pact, Bulkhead Design Pattern etc.

How will this course help me?

By attending this course, you do not have to spend time searching the Internet for Microservices interview questions. We have already compiled the list of the most popular and the latest Microservices Interview questions. 

Are there answers in this course?

Yes, in this course each question is followed by an answer. So you can save time in interview preparation.

What is the best way of viewing this course?

You have to just watch the course from beginning to end. Once you go through all the videos, try to answer the questions in your own words. Also mark the questions that you could not answer by yourself. Then, in second pass go through only the difficult questions. After going through this course 2-3 times, you will be well prepared to face a technical interview in Microservices architecture.

What is the level of questions in this course?

This course contains questions that are good for a Fresher to an Architect level. The difficulty level of question varies in the course from a Fresher to an Experienced professional.

What happens if Microservices technology changes in future?

From time to time, we keep adding more questions to this course. Our aim is to keep you always updated with the latest interview questions on Microservices.
