9 reasons why

Adaface Swift Test is the most accurate way to shortlist iOS -udviklers

Reason #1

Tests for on-the-job skills

The Swift 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:

I stand til at forstå det grundlæggende i Swift -programmeringssprog
I stand til at arbejde med forskellige datatyper i Swift
I stand til effektivt at bruge kontrolstrømningsstrukturer i Swift
I stand til at definere og arbejde med funktioner i Swift
I stand til at oprette og bruge klasser og genstande i Swift
I stand til at håndtere muligheder og pakke dem korrekt op i Swift
I stand til at håndtere fejl og undtagelser i Swift
I stand til at arbejde med samlinger som arrays og ordbøger i Swift
I stand til at forstå og bruge lukninger i Swift
I stand til at håndtere samtidighed og asynkrone opgaver i Swift

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.

What does the following Swift code output?
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 Swift 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.

What topics are covered in the Swift online test?

datatyper </H4> <p> Datatyper Definer den slags værdier, der kan gemmes og manipuleres i variabler eller konstanter. Denne færdighed måles i testen for at evaluere en kandidats forståelse af de forskellige datatyper, der er tilgængelige i SWIFT, som heltal, floats, strenge og arrays, og deres brug i skrivning af effektiv og typesikker kode. </p> <h4> Control Flow
kontrolstrøm henviser til strømmen af udførelse i et program, bestemt af betingede udsagn, sløjfer og grene. Denne færdighed måles i testen for at vurdere en kandidats evne til effektivt at kontrollere udførelsen af deres hurtige kode baseret på forskellige forhold, tage beslutninger og gentage handlinger efter behov.
funktioner
Funktioner I Swift er selvstændige kodeblokke, der udfører en bestemt opgave. Denne færdighed måles i testen for at evaluere en kandidats viden om at skabe, ringe og bruge funktioner i SWIFT, herunder parameterpasning, returtyper og overbelastningsbegrebet, hvilket hjælper med at skrive modulær og genanvendelig kode.
Fejlhåndtering
Fejlhåndtering i Swift er mekanismen til håndtering og reaktion på fejlbetingelser, der kan forekomme under udførelsen af et program. Denne færdighed måles i testen for at evaluere en kandidats viden om brug > <h4> samlinger </h4> <p> samlinger i Swift, som arrays, sæt og ordbøger, aktiverer opbevaring og organisering af flere værdier i en enkelt enhed. Denne færdighed måles i testen for at vurdere en kandidats forståelse af at arbejde med samlinger effektivt, herunder udførelse af fælles operationer som indsættelse, sletning, iteration og adgang til elementer, som er vigtige færdigheder i næsten alle ikke-trivielle programmeringsopgaver.
Concurrency
Samtidig i Swift er et programs evne til at udføre flere opgaver samtidig. Denne færdighed måles i testen for at evaluere en kandidats forståelse af at bruge Swifts samtidighedsmekanismer som samtidige køer, afsendelsesgrupper og async/venter på at skrive effektiv, skalerbar og responsiv kode, der kan håndtere samtidig udførelse og synkronisering korrekt.

Swift 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.
