9 reasons why

Adaface Ruby & Rails Test is the most accurate way to shortlist Ruby Developers

Reason #1

Tests for on-the-job skills

The Ruby & Rails Online Test helps recruiters and hiring managers identify qualified 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 time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

Bekwaam in Ruby Basics
Sterk begrip van Ruby Oeps
Bekend met rails fundamentals
Goed geïnformeerd in rails mvc
In staat om rust -API's in rails te bouwen
Bekwaam in robijncodering
Bekwaam in efficiënt afhandelen van uitzonderingen en fouten
Mogelijkheid om objectgeoriënteerde programmeerconcepten in Ruby te gebruiken
In staat om webtoepassingen te ontwikkelen met behulp van rails
In staat om RESTful API's in rails te ontwerpen en te implementeren

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.

View sample questions

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.

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 Ruby & Rails Test zal niet-googelbaar zijn.

🧐 Question
Easy Arrays Strings Arrays Strings	Try practice test
Check the following Ruby code: We want the following execution result: - Commit - PR - Merge What should we replace __BLOCK__ with to achieve this?
Medium Class and Self OOPs	Try practice test
What is the execution result of the following Ruby code?
Easy Exceptions Exceptions OOPs	Try practice test
What is the result of following Ruby code:
Medium New Class OOPs Singleton	Try practice test
Check the following Ruby code: Which all of the following statements should replace __BLOCK__ to have "Marvel" as execution result? A: Sample.new.class.ciao B: Sample.class.new.ciao C: Sample.new.ciao D: Sample.ciao
Hard Movie query problem	Try practice test
Our intern created the following model scope and they want to use in this view: Which of these code snippets they use to fetch the correct results, and avoid the N+1 query issue?
Easy Registration Queue Logic Queues	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 Visitors Count Strings Logic	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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Ruby & Rails 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.

What topics are covered in the Ruby & Rails Online Test?

Ruby OOPS
Deze vaardigheid Richt zich op objectgeoriënteerde programmeerconcepten in Ruby, zoals klassen, objecten, overerving en polymorfisme. Het is noodzakelijk om deze vaardigheid te meten om het vermogen van de kandidaat te evalueren om schaalbare en herbruikbare code te ontwerpen en te implementeren met behulp van de principes van objectgeoriënteerde programmering, wat cruciaal is bij het bouwen van complexe toepassingen.
Rails Fundamentals
Deze vaardigheid omvat de fundamentele aspecten van het Ruby on Rails Framework, inclusief de Model-View-Controller (MVC) architectuur, routing, actief record en database-integratie. Door deze vaardigheid te meten, kunnen recruiters de vaardigheid van de kandidaat beoordelen in het begrijpen van hoe rails framework werkt en hun vermogen om webtoepassingen te bouwen na best practices.
rails mvc
Deze vaardigheid richt zich specifiek op het model -View-Controller (MVC) patroon binnen het Ruby on Rails Framework. Het is belangrijk om deze vaardigheid te meten om het begrip van de kandidaat te evalueren van het effectief structureren en organiseren van code in een rails -toepassing, het scheiden van zorgen en het bevorderen van code herbruikbaarheid en onderhoudbaarheid.
REST API's in Rails </h4> <</h4> < P> Deze vaardigheid omvat de implementatie van RESTful API's met Ruby on Rails. Het meten van deze vaardigheid is cruciaal, omdat REST API's de ruggengraat zijn van de moderne webontwikkeling en het beoordelen van de expertise van de kandidaat bij het bouwen, ontwerpen en testen van API's helpt ervoor te zorgen dat ze de complexiteiten kunnen verwerken die betrokken zijn bij het ontwikkelen van robuuste webservices. </p> <h4> Ruby codering
Deze vaardigheid evalueert de vaardigheid van de kandidaat bij het schrijven van schone, efficiënte en idiomatische ruby code. Het is noodzakelijk om deze vaardigheid te meten om de coderingsstijl van de kandidaat, probleemoplossende vaardigheden en bekendheid met gemeenschappelijke Ruby-idiomen te beoordelen, die essentiële kwaliteiten zijn voor een competente Ruby-ontwikkelaar.

Ruby & Rails Hiring Test Veelgestelde vragen

Kan ik meerdere vaardigheden combineren in één aangepaste beoordeling?

Ja absoluut. Aangepaste beoordelingen zijn opgezet op basis van uw functiebeschrijving en bevatten vragen over alle must-have vaardigheden die u opgeeft.

Heeft u functies tegen latere of proctoring op hun plaats?

We hebben de volgende anti-cheating-functies op zijn plaats:

Niet-googelbare vragen
IP Proctoring
Web Proctoring
Webcam Proctoring
Plagiaatdetectie
Beveilig browser

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.
