9 reasons why

Adaface Data Analysis Assessment Test is the most accurate way to shortlist Dataanalytikers

Reason #1

Tests for on-the-job skills

The Data Analysis 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:

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

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 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

Data Analysis Hiring Test Ofte stillede spørgsmål

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.
