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 SQL online test assesses candidates' knowledge across the whole Web stack from HTML, CSS, and JavaScript on the Web front-end over Python on the back-end to SQL 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

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]
