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:

  • At forstå det grundlæggende i datamodellering inklusive enheder og relationer
  • Anvendelse af dataanalyseteknikker såsom aggregeringer og statistik
  • Anvendelse af grundlæggende elementer i forretningsanalyse
  • Fortolkning af data ved hjælp af diagrammer og grafer
  • Udførelse af dataforespørgsler og anvendelse af databaser ved hjælp af SQL
  • Udførelse af dataoperationer inklusive forudsigelser og afvigelser
  • Gennemførelse af dataundersøgelser inklusive korrelationer og placering
  • Brug af populære dataværktøjer som Excel
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.

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.

Reason #5

Designed for elimination, not selection

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

Data Analysis Hiring Test FAQS

Kan jeg bruge dataanalyttest til at ansætte dataforskere?

Ja, hvis din jobbeskrivelse nøje matcher kravene til dataanalytiker. Du kan også kontrollere vores standard dataforsker test for en mere fokuseret test.

Kan jeg evaluere Python eller R i dataanalyttesten?

Ja. Du kan have tre variationer af testen:

  • ** For dataanalytiker (Python) roller **: Sammen med standardspørgsmålets sæt har testen Python MCQ -spørgsmål og Python -kodningsspørgsmål
  • ** For dataanalytiker (R) roller **: Sammen med standardspørgsmålets sæt har testen R MCQ -spørgsmål og R -kodningsspørgsmål
  • For dataanalytikerroller, hvor kandidater kan kende enten ** Python eller R **: Sammen med standardspørgsmålets sæt vil kandidater blive bedt om at vælge deres foretrukne programmeringssprog mellem Python og R. Derefter bliver kandidaten spurgt om MCQ og Kodning af spørgsmål om det valgte programmeringssprog.

For at få en fornemmelse af, hvilken slags spørgsmål der vil blive stillet til at evaluere Python eller R-færdigheder, kan du gennemgå vores standard Python Online Test og r online tests.

Kan jeg evaluere Excel -færdigheder i dataanalyttesten?

Ja. Sammen med det standardspørgsmål, der er scenariebaserede MCQ-spørgsmål til evaluering af On-the-Job Microsoft Excel Experience. Du kan gennemgå vores standard Excel Online Test for at se, hvilke spørgsmål der vil blive brugt, og hvilke emner der vil blive evalueret.

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?
