Adaface Python Online Test is the most accurate way to shortlist Python Developers



Reason #1

Tests for on-the-job skills

The Python Online test helps recruiters and hiring managers to identify qualified Python developer candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves expensive engineering time by filtering out unqualified candidates.

The Adaface Python Online Test screen candidates for the typical skills recruiters look for in a Python developer:

  • Working with data structures (strings, lists, tuples, dictionaries and sets)
  • Processing images, CSVs, PDFs, and other files
  • In-built and custom modules and functions in Python like zip and filter
  • Object-oriented programming (Inheritance, Encapsulation, Polymorphism, and Data abstraction)
  • Handling database CRUD operations using Python
  • Generators, Comprehensions and Lambda Expressions
  • Testing, debugging and handling errors and exceptions in Python programs
  • Extracting data from websites using web scraping libraries like Selenium

The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for the role. Anti-cheating features enable you to be comfortable with conducting assessments online. The Python developer test is ideal for helping recruiters identify which candidates have the technical skills to do well on the job.

Reason #2

No trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface ->
Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

These are just a small sample from our library of 10,000+ questions. The actual questions on this Python Online Test will be non-googleable.

                        The function high_sess should compute the highest number of events per session of each user in the database by reading a comma-separated value input file of session data. The result should be returned from the function as a dictionary. The first column of each line in the input file is expected to contain the user’s name represented as a string. The second column is expected to contain an integer representing the events in a session. Here is an example input file:
                        
                        Tony,10
Stark,12
Black,25
Your program should ignore a non-conforming line like this one.
Stark,3
Widow,6
Widow,14
                        The resulting return value for this file should be the following dictionary: { 'Stark':12, 'Black':25, 'Tony':10, 'Widow':14 }
                        
                        What should replace the CODE TO FILL line to complete the function?

                        A startup company E-Motors is building driverless automated cars. The car contains a sensor that checks the road quality for the next N meters to decide the optimal speed at which the cars should move. We are given recorded data by the sensor in the form of an array, where each element of the array is the rating given to 1 meter of the road in sequence. 

The rating given by the sensor is from 1 to 100, where 100 represents the road with the best condition, and any rating above 60 is optimal. Find the longest stretch of road in meters that is categorized as optimal by the sensor.

The input is an array of "strings" which needs to be converted from string to integer/number inside the function.

    Reason #6

    Detailed scorecards & comparative results

    Reason #7

    Designed for elimination, not selection

    The most important thing while implementing the pre-employment Python Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

    Reason #8

    High completion rate

    Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

    This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

    Reason #9

    Advanced Proctoring


    How does the test differ for Senior and Junior developers?

    Our subject matter experts customize the test according to seniority in two ways:

    • The topics chosen for senior developers will be of higher level whereas for junior developers the topics will be around the core basics. This will ensure that the senior developers are tested on on-the-job skills that they are expected to have
    • Difficulty level of questions will be varied based on the seniority level. This way senior developers are vetted on in-depth usage of the core topics whereas junior developers are vetted on the knowledge of core topics

    Here are few topics assessed in Senior developer assessments:

    • Creating custom error classes
    • Advanced Collections: Named Tuples, Default Dictionary, Counters, Ordered Dictionary, Queues and Deques
    • Advanced Functions: Zipping, Unzipping, Evaluating expressions, Memory view, Mapping objects with lambda, Enumerating objects and Executing Python expressions
    • Generator functions with many yield statements and Generator expressions
    • Asynchronous programming using threads
    • Working with data science libraries like NumPy, Pandas
    • Metaprogramming and Introspection
    • Knowledge of decorators, closures, function factory and method chaining
    • Building REST APIs using Python
    • Managing project dependencies
    • Creating and publishing Python packages
    • Building Logger to indicate the problems
    • Metaclass: Built-in metaclasses and building custom metaclass

    • Plagiarism detection
    • Secure browser

    Read more about the proctoring features.

    How do I interpret test scores?

    The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

    What experience level can I use this test for?

    Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

    Does every candidate get the same questions?

    Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

    I'm a candidate. Can I try a practice test?

    No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

    What is the cost of using this test?

    You can check out our pricing plans.

    Can I get a free trial?
