This HTML/CSS, JavaScript, Python, and MongoDB Online Test Separates Good From Bad Hires

Screen with work-sample questions

Work-samples are the best predictor of work performance. 8,000+ companies use TestDome premium questions.

About the test

The HTML/CSS, JavaScript, Python, and MongoDB online test assesses the candidate's knowledge across the whole Web stack from HTML, CSS, and JavaScript on the Web front-end, to Python on the back-end with MongoDB for data access.

It's an ideal test for pre-employment screening. A good full stack Python developer needs to be able to use a wide range of technologies.

This online test requires candidates to solve coding problems and find and fix bugs in multiple technologies.

Sample public questions

Every user on your website has an image avatar that is displayed when they post a comment. You want to style these images differently from other images on your site. Add a CSS class named avatar that fulfils the following requirements:

  1. The avatar's border is rounded, so that it appears as a circle.
  2. The avatar's width and height are both 150px.
  3. The avatar has a solid border, has a width of 2px, and be colored gray.

For example, the avatar in the template should look like:

A university's Office of Admission keeps track of student majors. Each student can have a single major. Below is an example of how their system stores students, majors, and how it manipulates them:

students = [("Allen Anderson", "Computer Science"),
            ("Edgar Einstein", "Engineering"),
            ("Farrah Finn", "Fine Arts")]
     
def add_new_student(students, name, major):
    students.append((name, major))

def update_student(students, index, name, major):
    students[index] = (name, major)

def find_students_by_name(students, name):
    return [student for student in students if name in student[0]]

def get_all_majors(students):
    return [student[1] for student in students]
