9 reasons why

Adaface D3.JS Test is the most accurate way to shortlist D3.JS -udviklers

Reason #1

Tests for on-the-job skills

The D3.JS 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 manipulere og binde data til effektiv visualisering
Kapacitet til at vælge og ændre elementer i en D3 -visualisering
Færdighed i at skabe visualiseringer ved hjælp af D3.JS -bibliotek
Forståelse af skalering og akser for nøjagtig visuel repræsentation
Dygtighed til at skabe interaktive visualiseringer med brugervenlige funktioner
Kendskab til at bruge overgange til at forbedre visuelle effekter i D3.js
Adeptness i håndtering af begivenheder til dynamiske og responsive visualiseringer
Fortrolighed med layouts og hierarkier til organisering af visuelle elementer
Forståelse af kortlægning og fremskrivninger til geografiske visualiseringer
Evne til at tilpasse og style visualiseringer til at tilpasse sig kravene

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 #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment D3.JS 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 D3.JS 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.

What topics are covered in the D3.JS Online Test?

Valg og ændring af elementer
Denne færdighed fokuserer på at vælge og ændre elementer i DOM ved hjælp af D3.js . Det giver mulighed for præcis målretning af specifikke elementer og muliggør ændringer til deres attributter, stilarter og indhold.
Oprettelse af visualiseringer
Denne færdighed omfatter muligheden for at skabe interaktiv og visuelt tiltalende datavisualiseringer ved hjælp af D3.js. Det involverer at forstå, hvordan man repræsenterer data i forskellige former, såsom diagrammer, grafer, kort og mere.
skalering og akser
Denne færdighed involverer skalering af dataværdier, der passer til en visuel repræsentation og tilføje akser for at give referencepunkter til fortolkning af de visualiserede oplysninger. Det sikrer, at visualiseringerne nøjagtigt afspejler de underliggende data.
interaktiv visualisering
Denne færdighed fokuserer på at skabe interaktive datavisualiseringer, der giver brugerne mulighed for at udforske og interagere med de viste oplysninger. Det involverer at inkorporere interaktivitetsfunktioner såsom værktøjstip, svævefirmere og klikbare elementer.
overgange
Denne færdighed involverer at skabe glatte og animerede overgange mellem forskellige tilstande af en visualisering, såsom når data opdateres eller filtreres. Det forbedrer brugeroplevelsen ved at give visuelle signaler og formidle ændringer på en visuelt tiltalende måde.
Håndtering af begivenheder
Denne færdighed involverer at fange og håndtere forskellige brugerbegivenheder, såsom museklik, tastatur input og berøringsbevægelser for at udløse specifikke handlinger eller opdateringer i visualiseringen. Det muliggør brugerdrevne interaktioner og forbedrer den samlede anvendelighed af visualiseringen.
layouts og hierarkier </H4> <p> Denne færdighed involverer anvendelse af foruddefinerede layouts og hierarkier i D3.js for at arrangere og strukturere visuelle elementer i en visualisering. Det hjælper med at skabe organiserede og æstetisk tiltalende repræsentationer af komplekse data. </p> <h4> kortlægning og fremskrivninger
Denne færdighed fokuserer på kortlægningsdata til geografiske eller rumlige repræsentationer og bruger fremskrivninger til at omdanne dataene til forskellige Koordinatsystemer. Det muliggør oprettelse af interaktive kort og rumlige visualiseringer.
Tilpasning og styling
Denne færdighed involverer tilpasning og stil med visualiseringer ved hjælp af D3.js. Det inkluderer ændring af farver, skrifttyper, størrelser og andre visuelle aspekter, der skal tilpasses det ønskede design og æstetik.

D3.JS 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.
