Python (working with arrays) test: Online screening assessment to hire the best candidates

About the Python (coding): working with arrays test

Python is a high-level, general-purpose language that can be used in anything from web development to data science and machine learning. As an open-source programming language with a strong community, Python offers an expansive library of resources such as web frameworks, testing instruments, and data analysis tools.

One of the skills required of good Python developers is working with arrays. Arrays are special variables that hold collections of related values. Arrays allow developers to work with a large number of variables quickly and efficiently.

This test assesses candidates’ skills in working with Python arrays. The test provides candidates with a task description in the appropriate context and specifies the algorithms that need to be developed and the requirements to satisfy. It also provides a few examples to illustrate how the function should behave and asks candidates to solve the task. You can see a complete and functional example of a task by clicking the “preview questions” tab on this page.

Candidates can run their code to see if certain pre-defined inputs return the expected result. The test is scored automatically using a different set of test cases, which include more challenging corner cases. Once the test is complete, you can inspect the code of the candidate and play it back to interpret their thought process. You can also see the efficiency of the code shown in the results.

FAQs

What is the difference between an assessment and a test?
An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.
Can I add my own questions to an assessment?
Yes! Custom questions are great for testing candidates in your own unique way. We support the following question types: video, multiple-choice, coding, file upload, and essay. Besides adding your own custom questions, you can also create your own tests.
How do video questions work?
A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now." You can learn more about video questions here.
Can you explain how the other custom question types work?
Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
Can I customize an assessment with my company logo and color theme?
Yes! You can add your own logo and company color theme to your assessments. This is a great way to leave a positive and lasting brand impression on your candidates.
