Robust software development organizations often average four or five Software Engineers to a single Software Development Engineer in Test (SDET).
These individuals, also known as QA Engineers, create and manage the test scripts that test application functionality and verify visual layouts.
The most common tool used by these engineers is the Selenium open-source framework.
Selenium’s broad adoption is largely due to its flexibility. It automates testing across various web browsers such as Chrome, Mozilla, Firefox, Safari, and IE, using the Selenium WebDriver. With WebDriver, engineers can test events such as keystrokes, mouse clicks, drag-and-drop, and much more.
In addition, Selenium provides support for multiple programming languages through its own domain-specific language, Selenese. This enables engineers to write tests in all the major languages such as C#, Groovy, Java, Perl, PHP, Python, Ruby, and Scala, among others.
The prevalence and broad applicability of Selenium mean that most candidates will certainly reference it as a skill and the spectrum of true skills from novice to expert is quite large.
With HackerRank, you can now effectively evaluate Selenium skills during either the initial screen or remote technical interview—enabling you to truly identify candidates with the right level of Selenium expertise for your team.

How to evaluate Selenium expertise in HackerRank
Selenium skills are mapped to the QA Engineer/SDET role inside the HackerRank Skills Directory.
There are 10 Selenium questions in the library corresponding to the basic, intermediate and advanced skill sets. Each question is a single-page, browser-independent website that requires functional testing using Selenium. The questions evaluate critical Selenium skills including:
- Form Submission Automation: Questions to evaluate login, registration, and automation testing abilities for form submission on webpages.
- Web Authentication: Questions to evaluate operations such as handling Authentication/Login Popup.
- Web Scraping: Questions to set up web-scraping to extract useful data and information, web browser automation, among others.
- Data Entry Automation: Questions that evaluate data entry automation skills, including entry into web form from text or database.
In addition to Selenium itself, these questions also require basic proficiency with HTML, JavaScript, CSS, and Java Programming. They also require a solid understanding of the HTML Document Object Model (DOM) and experience with different types of locators like XPath, ID, and CSS.
Selenium is a framework. So Selenium questions are Projects-based questions inside HackerRank.
Projects-based questions are containerized, full-stack environments that are automatically deployed when the question is answered. Every aspect of these questions can be customized: the question itself, the test code, and the underlying environment.
Finally, just like all the questions mapped to roles in the HackerRank Skills Directory, each candidate score is benchmarked against your pool of candidates or the entire HackerRank community.
