  • Utilizing regular expressions in shell scripts
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.

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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Shell Online Assessment 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Shell Online Assessment 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.

What topics are covered in the Linux Shell Online Test?

  • Linux Shell

    The Linux shell refers to the command-line interface where users can interact with and control the operating system. It allows users to execute commands, manage files and processes, and perform various administrative tasks.

  • Command Line

    The command line is a text-based interface where users can enter commands to interact with the computer system. It provides more flexibility and control compared to graphical user interfaces, making it essential for managing and administering Linux systems.

  • Shell Scripting

    Shell scripting involves writing and executing scripts using the shell language, which allows automation and customization of Linux system tasks. It enables users to create complex sequences of commands and perform repetitive tasks efficiently.

  • Linux File System

    The Linux file system organizes and stores files and directories on a Linux system. Understanding the file system structure and knowing how to navigate, create, modify, and manage files and directories is crucial for effective system administration.

  • Process Management

    Process management involves monitoring and controlling running processes on a Linux system. This skill includes tasks such as starting, stopping, and prioritizing processes, as well as managing system resources and understanding process states.

  • Networking in Linux

    Networking in Linux refers to the configuration and management of network connections and protocols on a Linux system. It includes tasks such as setting up network interfaces, configuring IP addresses, managing routing tables, and troubleshooting network connectivity.

  • Permissions and Security

    Permissions and security in Linux involve managing access rights to files, directories, and system resources. This includes setting file permissions, managing user and group permissions, implementing security policies, and securing the system against unauthorized access and potential threats.

  • Package Management

    Package management in Linux involves managing software packages, including installation, updates, and removal. Linux distributions use package managers to handle dependencies, ensure system stability, and provide easy software management for users.

  • Text Processing

    Text processing in Linux involves manipulating and transforming text data using command-line tools and scripting. It includes tasks such as searching, replacing, sorting, filtering, and formatting text files, making it vital for tasks such as log file analysis and data processing.

  • Shell Variables

    Shell variables are used to store and manipulate data in the shell environment. They allow users to store values, perform calculations, and control the behavior of scripts and commands. Understanding shell variables is essential for effective shell scripting and system administration.

  • Regular Expressions

    Regular expressions are powerful patterns used to search, match, and manipulate text data. They provide a flexible and efficient way to perform complex string operations, making them an important skill for tasks such as data validation, text parsing, and pattern matching.

Linux Shell 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.
