Numpy online test: Pre-employment screening assessment to hire the best candidates

About the NumPy test

NumPy is one of the most powerful Python libraries and is used in industry for array computing. NumPy offers a convenient tool for working with data containing multi-dimensional arrays and matrix data structures. In our age of information and technologies, any business deals with massive amounts of data. It is crucial to efficiently organize that data to access and use it easily in everyday activities.

This NumPy test assesses candidates’ knowledge and skills in working with data using NumPy functionalities. These include the creation of NumPy arrays, which are user-friendly containers for storing information, manipulating those arrays, and navigating both basic and advanced built-in functions that can be used automatically instead of writing the code from scratch.

Candidates who perform well on this test demonstrate strong knowledge of NumPy and can find solutions for different problems while dealing with and manipulating data. This NumPy test is geared toward an intermediate level and requires not only theoretical but also practical experience to solve real-life scenarios that one can encounter when working with NumPy.

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.
What type of support do you offer?
Our team is always here to help. After you sign up, we’ll reach out to guide you through the first steps of setting up your TestGorilla account.
