React Native Online Test (React Native + JavaScript)

About the test:

The React Native Test uses scenario-based MCQ questions to evaluate a candidate's ability to build interactive, media-rich React Native applications and publish them using Google/ App stores. The questions assess core React Native concepts (components, state and props), state management fundamentals, accessing native features and proper usage of RESTful APIs. The test also has MCQs and coding questions to evaluate hands-on JavaScript programming skills.

Covered skills:

  • Core React Native (components; state; props)
  • Handling screen layouts
  • Functional components and Hooks
  • Styled-components

Adaface React Native Online Test (React Native + JavaScript) is the most accurate way to shortlist React Native Developers



Reason #1

Tests for on-the-job skills

De Native Test React evalueert de volgende REACT Native -onderwerpen die worden verwacht door managers van React Native Developers in te huren:

  • Hoe React, JavaScript en Native Componenten te gebruiken
  • Core React Native Concepts, zoals werken met componenten, staat en rekwisieten
  • Navigatie in React Native Apps
  • Styling en animeren van REACT Native Components-Styled-Componenten en native styling
  • Nieuwste react-native functies- hooks, context API, asyncstorage
  • Gebruik van native telefoonmogelijkheden zoals camera en vibratie
  • Google Maps API en het toevoegen van interactieve kaarten
  • Verbinding maken met een backend-server van uw app- asynchrone API's voor het ophalen en bijwerken
  • beveiliging-authenticatie, beperkende routes
  • Aangepaste lettertypen installeren

Bovendien heeft de beoordeling MCQ- en coderingsvragen om hands-on JavaScript-coderingsvaardigheden te evalueren. Het vermindert de administratieve overhead van het interviewen van te veel kandidaten en bespaart dure technische tijd door ongekwalificeerde kandidaten uit te filteren.

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.

Dit zijn slechts een klein monster uit onze bibliotheek met meer dan 10.000 vragen. De werkelijke vragen hierover React Native Online Test zal niet-googelbaar zijn.

Registration Queue
Logic
Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount.
For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition.
⚠️⚠️⚠️ Note:
- The first line of the input is the length of the array. The second line contains all the elements of the array.
- The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function.
- You need to "print" the final result (not return it) to pass the test cases.

For the example discussed above, the input will be:
5
20 70 -40 30 -10

Your code needs to print the following to the standard output:
20 70 30 -40 -10

Medium

Longest Road
logic
hashmaps
Solve
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.

Medium

Visitors Count
Strings
Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. 
Example:

Input:
WWMMWWCCC

Expected Output: 
4W3C2M

Explanation: 
‘W’ has the highest count, then ‘C’, then ‘M’. 
⚠️⚠️⚠️ Note:
- The input is already parsed and passed to a function.
- You need to "print" the final result (not return it) to pass the test cases.
- If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’.
- If any of them have the same count, the output should follow this order - M, W, C.

Met Adaface konden we ons eerste screeningproces optimaliseren met meer dan 75%, waardoor we kostbare tijd vrijmaken voor zowel wervingsmanagers als ons talent -acquisitieteam!


Brandon Lee, Hoofd van mensen, Love, Bonito

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment React Native 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 #6

1 click candidate invites

Email invites: You can send candidates an email invite to the React Native Online Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

Reason #7

Detailed scorecards & comparative results

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

Lees meer over de Proctoring -functies.

Hoe interpreteer ik testscores?

Het belangrijkste om in gedachten te houden is dat een beoordeling een eliminatietool is, geen selectietool. Een vaardighedenbeoordeling is geoptimaliseerd om u te helpen kandidaten te elimineren die niet technisch gekwalificeerd zijn voor de rol, het is niet geoptimaliseerd om u te helpen de beste kandidaat voor de rol te vinden. Dus de ideale manier om een ​​beoordeling te gebruiken is om een ​​drempelscore te bepalen (meestal 55%, wij helpen u benchmark) en alle kandidaten uit te nodigen die boven de drempel scoren voor de volgende interviewrondes.

Voor welk ervaringsniveau kan ik deze test gebruiken?

Elke ADAFACE -beoordeling is aangepast aan uw functiebeschrijving/ ideale kandidaatpersonage (onze experts van het onderwerp zullen de juiste vragen kiezen voor uw beoordeling uit onze bibliotheek van 10000+ vragen). Deze beoordeling kan worden aangepast voor elk ervaringsniveau.

Krijgt elke kandidaat dezelfde vragen?

Ja, het maakt het veel gemakkelijker voor u om kandidaten te vergelijken. Opties voor MCQ -vragen en de volgorde van vragen worden gerandomiseerd. We hebben anti-cheating/proctoring functies. In ons bedrijfsplan hebben we ook de optie om meerdere versies van dezelfde beoordeling te maken met vragen over vergelijkbare moeilijkheidsniveaus.

Ik ben een kandidaat. Kan ik een oefentest proberen?

Nee. Helaas ondersteunen we op dit moment geen oefentests. U kunt echter onze voorbeeldvragen gebruiken voor praktijk.

Wat zijn de kosten van het gebruik van deze test?

U kunt onze [prijsplannen] bekijken (https://www.adaface.com/pricing/).

Kan ik een gratis proefperiode krijgen?

Ja, u kunt gratis aanmelden en een voorbeeld van deze test.

Ik ben net naar een betaald plan verhuisd. Hoe kan ik een aangepaste beoordeling aanvragen?
