In this article, we unpack HackerRank enabled capabilities to assess Kubernetes’ skills. Before we proceed, to learn how to create, and score DevOps questions, please see here.
Kubernetes questions help you assess candidates’ ability to think about scaling, distributed computing, and managing containers altogether. This also usually relates also to other skills like Docker and DevOps in general.
When a candidate takes a test consisting of Kubernetes questions, we set up their own sandbox Linux virtual machine with Docker and Kubernetes preinstalled to log in remotely through SSH. Developers can be asked to perform tasks such as: creating clusters, listing clusters, management of containers in clusters. For instance, solving HackerRank’s Kubernetes questions tests both theoretical and practical knowledge of the skill. For example, assessing the knowledge of what node stands for in Kubernetes terminology and then implement a solution to display a list of nodes inside the cluster. Learn more about which Kubernetes competencies are recommended to assess candidates proficiency levels by visiting our Kubernetes Skill Directory here.
Question types that can be used to assess Kubernetes
Some of the most common ways to assess Kubernetes Skills are as below:
- Hands-on Tasks (Recommended)
- Multiple Choice Questions
- System Design Questions
Real-world or Hands-on tasks and questions require candidates to dive deeper and actually demonstrate their skill proficiency. Using the hands-on questions in our library, candidates can be measured on practical demonstrations and multiple solution paths. Kubernetes based questions in the HackerRank library assess the deployment of a MySQL pod on Kubernetes cluster via Secrets, creation, and configuration of clusters, to name a few. Some examples of questions in our library are as below.
Multiple-choice questions [MCQs], in general, assess conceptual knowledge and understanding of a skill. The highest and most accurate insight into a candidate's Kubernetes skill is available by using System Design Questions. Customers can leverage whiteboard solutions on HackerRank Interviews as well as Diagram questions to sketch out cluster organization, nodes inside clusters, what containerized apps are used, on what backends, and so on. These questions provide insights into the candidate's thought process.
