Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment NextJs 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 NextJs 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.

  • Bygning af solidt fundament i HTML/CSS Fundamentals

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 NextJS Test?

  • styling og konfiguration af næste.js komponenter

    Denne færdighed evaluerer muligheden for at style og konfigurere komponenter i Next.js, en populær ramme for bygning af react -applikationer. Det tester viden om CSS-in-JS-biblioteker, komponentstylingmetoder og hvordan man udnytter næste.js specifikke funktioner til styling.

  • React Fundamentals

    Denne færdighed måler forståelsen af ​​grundlæggende React -koncepter og principper såsom komponenter, rekvisitter, tilstand og livscyklusmetoder. Den vurderer muligheden for at opbygge reaktiske applikationer og bruge almindeligt anvendte reaktmønstre.

  • React Hooks

    React Hooks er en funktion, uden at skrive klassekomponenter. Denne færdighed evaluerer dygtigheden i at bruge kroge som UseState, Useeffect og brugerdefinerede kroge til at styre tilstands- og bivirkninger i en funktionel komponent.

  • JavaScript ES6 Fundamentals

    ES6 (ECMASCRIPT 2015) IS En større opdatering til JavaScript -sproget, der introducerer nye funktioner og syntaksforbedringer. Denne færdighed vurderer forståelsen af ​​ES6 -koncepter såsom pilfunktioner, destruktion, spredt syntaks, moduler og mere.

  • Next.js Routing

    Next.js giver routingfunktioner ud af Boks, hvilket muliggør nem navigation mellem sider. Denne færdighed evaluerer viden om næste.js routingmekanismer, dynamisk routing, indlejrede ruter og hvordan man håndterer routingrelaterede opgaver i en næste.js-applikation.

  • server-side gengivelse </h4> <P > Server-side Rendering (SSR) er en teknik, der gør det muligt at gengives reagerende komponenter på serveren og sendes til klienten som HTML. Denne færdighed måler muligheden for at implementere SSR ved hjælp af Next.js og forstå fordelene og overvejelserne ved gengivelse af serversiden. </p> <h4> API-integration

    Denne færdighed evaluerer muligheden for at integrere API'er i en Next.js applikation. Det tester viden om at fremstille HTTP -anmodninger, håndtere API -svar, godkendelse/autorisation og datamanipulation ved hjælp af Next.js -værktøjer og biblioteker.

  • statsstyring

    I komplekse react -applikationer, statsstyring bliver afgørende for at styre applikationens globale tilstand. Denne færdighed vurderer forståelsen af ​​forskellige statsstyringsmetoder som Redux, Context API, og hvordan man implementerer dem i Next.js.

  • Data Hentning

    Hentning af data fra eksterne API'er er en fælles opgave i moderne webudvikling. Denne færdighed måler evnen til at hente og forbruge data ved hjælp af forskellige tilgange, såsom gengivelse på serversiden, SWR (uaktuelt-while-revurdere) og klientside-data, der henter med næste.js.

  • html/ CSS Fundamentals

    Denne færdighed tester grundlæggende viden om HTML og CSS, herunder forståelse af HTML -tags, CSS -vælgere, kassemodel, layoutteknikker og responsive designprincipper.

NextJS 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.
