🧐 Question🔧 Skill💪 Difficulty⌛ Time
Netflix Fav Movie
We are building a Netflix clone where users can stream movies. Our service tracks and logs usage for each user. Each log contains the name of the movie, length of the movie (in minutes) and number of minutes of the movie watched by the user. Can you help with some data analysis?
Our code needs to return the Favorite movie: the name of the movie with the highest percentage of movie watched by the user. If a user watched 30mins out of 60mins for movie1 (50%) and 75min out of 100min of movie2 (75%), the movie with the highest percentage of movie watched by the user is movie2 (Assume that the values are such that there can never be a tie for this spot).

    FAQs

    What is a custom assessment?

    Every role is different and requires a custom assessment to identify top candidates efficiently. Adaface subject matter experts understand your job description/ role requirements and pick the most relevant questions from our library of 10000+ questions to create a technical assessment that helps you find the qualified candidates in your candidate pipeline quickly. All custom assessments are set up based on the job description, role requirements, must-have skills, experience level and salary range within a maximum of 48 hours and you will get an email notification once it goes live.

    Check out a sample assessment here (no credit card required).

    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.
