Reason #2

No trick questions

no trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface
Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

These are just a small sample from our library of 10,000+ questions. The actual questions on this Kubernetes Online Test will be non-googleable.

🧐 Question

ConfigMap and Secrets Interaction
Resource Management
Security
Solve
In a Kubernetes cluster, you are working on configuring a new deployment that should be able to access specific environment variables through both ConfigMap and Secrets resources. The deployment YAML is structured as follows:
 image
You have applied the above YAML successfully without any errors. Now, you are about to configure a service to expose the deployment. Before doing that, you want to confirm the security and setup implications.

Based on the above configuration, which of the following statements are true?
1. The DATABASE_PASSWORD will be mounted as an environment variable in plain text.
2. The ConfigMap data can be updated and the changes will be reflected automatically in the running pods without any need for a redeployment.
3. If a potential attacker gains access to the cluster, they would be able to retrieve the DATABASE_PASSWORD in plain text from the secrets resource as it is defined in stringData.
4. The APP_ENV and DATABASE_URL values are securely stored and cannot be accessed by non-admin users.
5. If a new container in the same pod is created, it would automatically have the DATABASE_PASSWORD environment variable configured.

Medium

Ingress from namespace
Network
Network Policies
Solve
You are tasked with deploying a Kubernetes network policy. Here are the specifications:

- Name of the policy: adaface-namespace
- Policy to be deployed in ‘chatbot’ namespace
- The policy should allow ALL traffic only from ‘tester’ namespace
- Policy should not allow communication between pods in the same namespace
- Traffic only from ‘tester’ namespace is allowed on all ports
Which of the following configuration files is BEST suited to create required dependencies and deploy the network policy?
 image

Medium

Pod Affinity and Resource Quota Compliance
Pod Scheduling
Resource Management
Solve
You are working on a Kubernetes project where you need to ensure that certain pods get scheduled on nodes based on the presence of other pods and to limit the amount of resources that can be consumed in a namespace. You have been given the following YAML file which contains a combination of a pod definition and a resource quota:
 image
With the application of the above YAML configuration, assess the validity of the statements and choose the correct option that lists all the true statements.
1. The critical-pod will only be scheduled on nodes where at least one pod with a label security=high is already running.
2. The critical-pod is adhering to the resource quotas defined in the compute-quota.
3. The compute-quota restricts the namespace to only allow a total of 1 CPU and 1Gi memory in requests and 2 CPUs and 2Gi memory in limits across all pods.
4. If a node has multiple pods labeled with security=high, the critical-pod can potentially be scheduled on that node, given other scheduling constraints are met.
5. The critical-pod exceeds the defined memory request quota as per the compute-quota.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Kubernetes Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Kubernetes Online Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

Kubernetes Hiring Test FAQs

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

  • Non-googleable questions
  • IP proctoring
  • Screen proctoring
  • Web proctoring
  • Webcam proctoring
  • Plagiarism detection
  • Secure browser
  • Copy paste protection

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

Yes, you can sign up for free and preview this test.
