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 }

Why You Should Use This Python Online Test

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.

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

Distribution Of Test Scores

The actual score distribution will vary based on your candidate pipeline quality, but you should typically expect ~20% of the candidates to do well on Adaface assessments.

The score distribution for our assessments follow the normal curve. This is a good sign- standardized tests like SAT and GRE follow the normal distribution (bell curve).

Status quo assessments typically have the exact opposite of the bell curve (too many candidates getting close to 0, too many candidates getting close to 100 and too few candidates in the middle). This is typically because they focus on theoretical questions or trick questions, which are very binary in nature- either you know the trick/ theory or you don’t.

    Yes. You can screen multiple skills in a single test. You can review our standard Python Django test and HTML/ CSS test to understand what kind of questions would be used to evaluate those skills. Once you purchase a plan, you can get a customized assessment with questions to evaluate all the must-have skills of your job description.

    Can I evaluate web scraping technologies like Selenium and Python in the same test?

    Yes. We support testing Selenium and Python in the same test. You can check our Selenium test to understand how we design Selenium questions. The final assessment will have scenario-based MCQ questions to evaluate Selenium, Python and coding questions to evaluate hands-on Python programming skills.

    Can I use this test to evaluate Data Scientists?

    Can I combine multiple skills into one custom assessment?

    Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.

    How is Adaface different from other assessment tools?

    We believe that status quo tech assessment platforms are not a fair way for companies to evaluate engineers because they focus on trick questions/ puzzles/ niche algorithms. We started Adaface to help companies find great engineers by assessing on-the-job skills required for a role. Read more about why we started Adaface.

    Here's what's different with Adaface:

    • High quality non-googleable questions that test for on-the-job skills as opposed to theoretical knowledge.
    • A friendly conversational assessment with a chatbot, instead of sending a "test" to a candidate. This translates to a higher completion rate. Adaface assessments (86% candidate completion rate), as opposed to traditional tests (40-50% candidate completion rate)
    • Customized assessments for 700+ skills at different experience levels.

    Do you have any anti-cheating or proctoring features in place?

    We have the following anti-cheating features in place:

    • Web proctoring
    • Webcam proctoring
    • Plagairism detection
    • Non-googleable questions
    • 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?

    The platform is completely self-serve, so here's one way to proceed:

    • You can sign up for free to get a feel for how it works.
    • The free trial includes one sample assessment (Java/ JavaScript) that you will find in your dashboard when you sign up. You can use it to review the quality of questions, and the candidate experience of a conversational test on Adaface.
    • To review the quality of questions, you can also review our public questions for 50+ skills here.
    • Once you're convinced that you want to try it out with real assessments and candidates, you can pick a plan according to your requirements.

    I just moved to a paid plan. How can I request a custom assessment?
