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:

Dygtige til Ruby Basics
Stærk forståelse af Ruby Ups
Kendskab til Rails Fundamentals
Kyndig i Rails MVC
I stand til at bygge REST API'er i skinner
Dygtige til rubinkodning
Dygtige til effektivt håndtering af undtagelser og fejl
Evne til at bruge objektorienterede programmeringskoncepter i Ruby
I stand til at udvikle webapplikationer ved hjælp af skinner
I stand til at designe og implementere afslappede API'er i skinner

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.

Dette er kun en lille prøve fra vores bibliotek med 10.000+ spørgsmål. De faktiske spørgsmål om dette Ruby & Rails test vil være ikke-gåbart.

🧐 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
Denne færdighed Fokuserer på objektorienterede programmeringskoncepter i Ruby, såsom klasser, genstande, arv og polymorfisme. Det er nødvendigt at måle denne færdighed til at evaluere kandidatens evne til at designe og implementere skalerbar og genanvendelig kode ved hjælp af principperne for objektorienteret programmering, som er afgørende for at opbygge komplekse applikationer.
Rails Fundamentals
Denne færdighed omfatter de grundlæggende aspekter af Ruby On Rails Framework, herunder Model-View-Controller (MVC) arkitektur, routing, aktiv rekord og databaseintegration. Måling af denne færdighed giver rekrutterere mulighed for at vurdere kandidatens dygtighed til at forstå, hvordan Rails Framework fungerer og deres evne til at opbygge webapplikationer efter bedste praksis.
Rails MVC
Denne færdighed fokuserer specifikt på modellen -View-controller (MVC) mønster inden for Ruby On Rails Framework. Det er vigtigt at måle denne færdighed til at evaluere kandidatens forståelse af, hvordan man effektivt skal strukturere og organisere kode i en Rails -applikation, adskille bekymringer og fremme kode genanvendelighed og vedligeholdelighed.
REST API'er i Rails </h4> < P> Denne færdighed dækker implementeringen af RESTful API'er ved hjælp af Ruby on Rails. Måling af denne færdighed er afgørende, da REST API'er er rygraden i moderne webudvikling, og vurdering af kandidatens ekspertise inden for opbygning, design og test af API'er hjælper med at sikre, at de kan håndtere de kompleksiteter, der er involveret i udviklingen af robuste webtjenester. </p> <h4> Ruby Coding
Denne færdighed evaluerer kandidatens dygtighed i skrivning ren, effektiv og idiomatisk Ruby -kode. Det er nødvendigt at måle denne færdighed til at vurdere kandidatens kodningsstil, problemløsningsevner og fortrolighed med almindelige rubin-idiomer, som er væsentlige kvaliteter for en kompetent Ruby-udvikler.

Ruby & Rails Hiring Test Ofte stillede spørgsmål

Kan jeg kombinere flere færdigheder i en brugerdefineret vurdering?

Ja absolut. Brugerdefinerede vurderinger er oprettet baseret på din jobbeskrivelse og vil omfatte spørgsmål om alle must-have-færdigheder, du angiver.

Har du nogen anti-cheating eller proctoring-funktioner på plads?

Vi har følgende anti-cheating-funktioner på plads:

Ikke-gåbare spørgsmål
IP Proctoring
Webproctoring
Webcam Proctoring
Detektion af plagiering
Sikker browser

Læs mere om Proctoring Features.

Hvordan fortolker jeg testresultater?

Den primære ting at huske på er, at en vurdering er et elimineringsværktøj, ikke et udvælgelsesværktøj. En færdighedsvurdering er optimeret for at hjælpe dig med at eliminere kandidater, der ikke er teknisk kvalificerede til rollen, den er ikke optimeret til at hjælpe dig med at finde den bedste kandidat til rollen. Så den ideelle måde at bruge en vurdering på er at beslutte en tærskelværdi (typisk 55%, vi hjælper dig med benchmark) og inviterer alle kandidater, der scorer over tærsklen for de næste interviewrunder.

Hvilken oplevelsesniveau kan jeg bruge denne test til?

Hver Adaface -vurdering tilpasses til din jobbeskrivelse/ ideel kandidatperson (vores emneeksperter vælger de rigtige spørgsmål til din vurdering fra vores bibliotek på 10000+ spørgsmål). Denne vurdering kan tilpasses til ethvert erfaringsniveau.

Får hver kandidat de samme spørgsmål?

Ja, det gør det meget lettere for dig at sammenligne kandidater. Valgmuligheder for MCQ -spørgsmål og rækkefølgen af spørgsmål randomiseres. Vi har anti-cheating/proctoring funktioner på plads. I vores virksomhedsplan har vi også muligheden for at oprette flere versioner af den samme vurdering med spørgsmål om lignende vanskelighedsniveauer.
