9 reasons why

Adaface Rust Test is the most accurate way to shortlist Rustudviklers

Reason #1

Tests for on-the-job skills

The Rust 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:

Evne til at skrive korrekt og effektiv rustkode ved hjælp af standardoperatører og syntaks
Evne til at arbejde med enums og mønstermatchning i rust
Evne til at forstå og bruge generiske strukturer i rust
Evne til at arbejde med smarte pointer i Rust
Evne til at forstå og implementere referencetælling i rust
Evne til at bruge trådbassiner og arbejdere i rust
Forståelse af ejerskabskoncepter i Rust
Evne til at arbejde med løkker og strenge i rust
Forståelse af oops -koncepter i rust
Evne til at arbejde med generiske iteratorer i rust
Forståelse af samtidighedskoncepter i rust
Evne til at arbejde med tråde i rust

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.

How we design questions

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

🧐 Question
Easy Join Handles Concurrency	Solve
Review the following two Rust code snippets: Notice the handle.join().unwrap() line added in snippet two. Pick the correct statements: A: Snippet one prints 1 to 5 in the spawned thread and 1 to 3 in the main thread always. B: Snippet one prints 1 to 3 in the main thread but spawned thread might be closed before it prints all the numbers. C: Snippet two prints 1 to 5 in the spawned thread and 1 to 3 in the main thread always. D: Snippet two prints 1 to 3 in the main thread but the spawned thread might be closed before it prints all the numbers.
Medium Mutable Sample Structs Variables and Mutability	Solve
What does the following Rust code print?
Medium Passed Function Closures	Solve
Review the following code and pick the correct statements: A: The code prints 1223 B: The code prints 1111 C: The code prints 1234 D: The callPassedFunction(passedFunction) on line 7 makes a copy of passedFunction to become the argument of callPassedFunction. The copy gets executed and the x of copy becomes 2, but the original closure still holds a value of 1 for its captured x. E: The callPassedFunction(passedFunction) on line 7 makes a copy of passedFunction to become the argument of callPassedFunction. The copy gets executed and x of the copy and the origin both become 2.
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 Rust 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.

Science behind Adaface tests

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the Rust online test?

enums og mønstermatchning </h4> <p > Enums og mønstermatchning i rust er kraftfulde værktøjer til styring af komplekse datatyper og at tage beslutninger baseret på forskellige sager. Denne færdighed skal måles for at vurdere en kandidats evne til at arbejde med og manipulere datastrukturer i rust ved hjælp af enum -typer og mønstermatchningskonstruktioner Datakonstruktioner, der kan arbejde med forskellige typer. Måling af denne færdighed hjælper med at vurdere en kandidats forståelse af generiske programmeringskoncepter i rust og deres evne til at skrive fleksibel og effektiv kode ved hjælp af generiske strukturer der giver yderligere funktionalitet og sikkerhedsgarantier sammenlignet med regelmæssige pointer. Denne færdighed skal måles for at evaluere en kandidats færdighed i håndtering af hukommelse, undgå hukommelseslækager og bruge avancerede hukommelsesstyringsfunktioner med smarte pointer. </p> <h4> Referenceoptælling
Referencetælling i Rust involverer styring Ejerskab og levetid for delte data gennem referencetællinger. Evaluering af denne færdighed hjælper med at bestemme en kandidats forståelse af hukommelsesstyring i rust og deres evne til at håndtere delt ressourceejerskab med referencetælling.
trådbassiner og arbejdstager
trådbassiner og arbejdstagere er vigtige for Samtidig og parallelisme i rust. Måling af denne færdighed er vigtig for at evaluere en kandidats viden om Rusts samtidighedsmekanismer, deres evne til at udnytte trådbassiner til effektiv udførelse og deres forståelse af at skabe arbejdertråde til distribution af arbejdsbelastninger.
ejerskabskoncepter </H4> < P> ejerskab er et grundlæggende koncept i rust, der bestemmer, hvordan hukommelse tildeles, åbnes og renses op. Evaluering af denne færdighed hjælper med at vurdere en kandidats greb om unikt ejerskab, låntagning og levetid i rust, hvilket gør dem i stand til at skrive sikker og effektiv kode Konstruktioner, der bruges på næsten ethvert programmeringssprog, og rust er ingen undtagelse. Måling af denne færdighed giver rekrutterere mulighed for at vurdere en kandidats fortrolighed med loopstrukturer og deres evne til at manipulere og behandle strengdata i rust. </p> <h4> oops-koncepter
oops (objektorienterede programmeringssystemer) koncepter) koncepter er relevante på mange programmeringssprog, inklusive rust. Evaluering af denne færdighed hjælper rekrutterere med at bestemme en kandidats forståelse af indkapsling, arv, polymorfisme og andre OOP -principper og deres evne til at anvende disse begreber i rustudvikling.
generiske iteratorer
generiske iteratorer er vigtige i Rust for at udføre forskellige operationer inden for indsamling af data. Denne færdighed skal måles for at evaluere en kandidats færdigheder i at bruge og manipulere iteratorer i rust, som hjælper med at skrive kortfattet, ekspressiv og effektiv kode Et program til at udføre flere opgaver samtidig. Måling af denne færdighed hjælper med at bestemme en kandidats forståelse af Rusts samtidighedsmekanismer, såsom tråde, kanaler og låse, og deres evne til at skrive samtidig kode, der er både korrekt og effektiv.

Rust 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.
