Reason #2

No trick questions

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.

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

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 JavaScript, HTML/CSS, C# & SQL 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
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the JavaScript, HTML/CSS, C# & SQL 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.

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 JavaScript, HTML/CSS, C# & SQL Online Test?

  • ES6 -syntaks

    ES6 -syntaks henviser til den nyeste version af JavaScript, også kendt også Som ECMASCRIPT 2015. Det introducerer nye funktioner og syntaksforbedringer for at gøre JavaScript -koden mere kortfattet og udtryksfuld. Måling af denne færdighed hjælper med at vurdere en kandidats fortrolighed med moderne JavaScript -udviklingspraksis og deres evne til at bruge avancerede sprogfunktioner.

  • async/ afventer i JS </ h4> <p> async/ afventer i JavaScript er et programmeringsmønster Det forenkler asynkron kodeudførelse. Det giver udviklere mulighed for at skrive asynkrone funktioner i en synkron stil, hvilket gør koden lettere at læse og vedligeholde. Måling af denne færdighed er vigtig, da den tester en kandidats forståelse af håndtering af asynkrone operationer, såsom API -anmodninger eller datahentning, i JavaScript Til de grundlæggende koncepter og syntaks for HTML og CSS, byggestenene til webudvikling. Det inkluderer emner som HTML -tags, CSS -vælgere, stylingelementer og oprettelse af layouts. Det er vigtigt at måle denne færdighed, da den vurderer en kandidats evne til at oprette og style basale websider ved hjælp af HTML og CSS. </p> <h4> DOM -håndtering med JS

    DOM -håndtering med JavaScript er manipulation og interaktion med dokumentobjektmodellen (DOM) ved hjælp af JavaScript. Det involverer at vælge elementer, ændre deres egenskaber, tilføje eller fjerne elementer og reagere på brugerbegivenheder. Måling af denne færdighed er afgørende, da den vurderer en kandidats færdigheder i dynamisk manipulering af websider og skabelse af interaktive brugergrænseflader ved hjælp af JavaScript C# Programmeringssprog. Det inkluderer emner som variabler, datatyper, kontrolstrøm, funktioner, klasser og objektorienterede programmeringskoncepter. Det er vigtigt at måle denne færdighed, da den tester en kandidats forståelse af C# -sproget og deres evne til at skrive ren og effektiv kode.

  • C# oops

    C# oops (objektorienteret programmering) involverer Design og implementering af objektorienterede løsninger ved hjælp af C# sprogfunktioner som klasser, arv, polymorfisme og indkapsling. Måling af denne færdighed er afgørende, da den vurderer en kandidats evne til at skrive velstruktureret og vedligeholdelig kode ved hjælp af objektorienterede principper.

  • SQL CRUD-operationer

    SQL CRUD (Opret, læs, opdatering , Slet) operationer repræsenterer de grundlæggende databaseoperationer udført ved hjælp af SQL (struktureret forespørgselssprog). Det inkluderer indsættelse af data i en database, hentning af data fra en database, opdatering af eksisterende data og sletning af data. Det er vigtigt at måle denne færdighed, da den evaluerer en kandidats evne til at arbejde med databaser og udføre vigtige datamanipulationsopgaver ved hjælp af SQL.

  • SQL -sammenføjning og indekser </H4> <p> SQL tilslutter sig og indekser er teknikker, der bruges til Effektiv og optimeret dataindhentning fra relationelle databaser. SQL slutter sig til at tillade at kombinere data fra flere tabeller baseret på specificerede betingelser, mens indekser forbedrer databasens søgning og hentning. Måling af denne færdighed er afgørende, da den tester en kandidats forståelse af avancerede SQL -koncepter og deres evne til at optimere forespørgsler for bedre databaseydelse. </p> <h4> kodning

    Kodningsevne henviser til evnen til at skrive rent rent , effektiv og funktionel kode på det valgte programmeringssprog. Måling af denne færdighed hjælper med at vurdere en kandidats ekspertise i at oversætte problemangivelser til arbejdskode, anvende programmeringskoncepter og følge bedste praksis for at producere pålidelige softwareløsninger.

JavaScript, HTML/CSS, C# & SQL 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.

Jeg er kandidat. Kan jeg prøve en øvelsestest?

Nej. Desværre understøtter vi ikke praksisforsøg i øjeblikket. Du kan dog bruge vores eksempler på spørgsmål til praksis.

Hvad er omkostningerne ved at bruge denne test?

Du kan tjekke vores prisplaner.

Kan jeg få en gratis prøve?

Ja, du kan tilmelde dig gratis og forhåndsvise denne test.

Jeg flyttede lige til en betalt plan. Hvordan kan jeg anmode om en brugerdefineret vurdering?

Her er en hurtig guide til hvordan man anmoder om en brugerdefineret vurdering på adaface.
