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.

What topics are covered in the Data Analysis Test?

Grunnleggende om dataanalyse (Aggregations and Statistics)
Dataanalyse innebærer å undersøke, rensende, transformere og modellere data for å avdekke meningsfull innsikt. Denne ferdigheten måles i testen for å vurdere kandidatens kjennskap til nøkkelbegreper som aggregasjoner (summer, gjennomsnitt osv.) Og statistiske tiltak (gjennomsnitt, median, etc.), slik at de kan utforske, oppsummere og tolke data nøyaktig. < /p> <h4> Fundamentals for forretningsanalyse </h4> <p> Forretningsanalyse innebærer å identifisere forretningsbehov, anbefale løsninger og legge til rette for implementering av endringer. Denne ferdigheten måles i testen for å måle kandidatens forståelse av essensielle teknikker og verktøy som brukes i forretningsanalyse, for eksempel SWOT -analyse, interessentanalyse og krav om krav, for å sikre deres ferdigheter i å analysere og løse forretningsproblemer. H4> Datatolkning (diagrammer og grafer) </h4> <p> Datatolkning innebærer forståelse og henter innsikt fra visuelle representasjoner som diagrammer og grafer. Denne ferdigheten måles i testen for å evaluere kandidatens evne til å tolke og analysere data visuelt, slik at de effektivt kan kommunisere viktige funn og trender til interessenter.
Data -spørsmål og databaser (SQL) </h4> < P> Dataforespørsler og databaser involverer bruk av Structured Query Language (SQL) for å hente, manipulere og administrere data i relasjonsdatabasesystemer. This skill is measured in the test to assess the candidate's proficiency in writing SQL queries, ensuring they can effectively extract and manipulate data to support various business requirements.</p><h4>Data operations (Predictions and Anomalies)</h4>< P> Dataoperasjoner innebærer å forutsi fremtidige utfall og identifisere anomalier eller outliers i data. Denne ferdigheten måles i testen for å finne ut kandidatens kunnskap og evne til å bruke statistiske teknikker, maskinlæringsalgoritmer og data mining-metoder for å utføre prediktiv modellering og anomalideteksjon for verdifull datadrevet innsikt. (Korrelasjoner og rangering)
Dataundersøkelser innebærer å utforske sammenhenger mellom variabler, identifisere korrelasjoner og rangering av data basert på spesifikke kriterier. Denne ferdigheten måles i testen for å evaluere kandidatens evne til å analysere og tolke statistiske forhold, slik at de kan avdekke mønstre, ta informerte beslutninger og identifisere viktige faktorer som påvirker resultatene.

Data Analysis Hiring Test Vanlige spørsmål

Kan jeg bruke dataanalytikertest for å ansette dataforskere?

Ja, hvis stillingsbeskrivelsen din samsvarer med kravene til dataanalytiker. Du kan også sjekke vår standard Data Scientist Test for en mer fokusert test.

Kan jeg evaluere Python eller R i Data Analyst -testen?

Ja. Du kan ha tre varianter av testen:

** For dataanalytiker (Python) roller **: Sammen med standard spørsmålssettet vil testen ha Python MCQ -spørsmål og Python -kodingsspørsmål
** For dataanalytiker (R) roller **: Sammen med standard spørsmålssettet vil testen ha R MCQ -spørsmål og R -kodingsspørsmål
For dataanalytikerroller der kandidater kan vite enten ** Python eller R **: Sammen med standard spørsmålssettet, vil kandidater bli bedt om å velge sitt foretrukne programmeringsspråk mellom Python og R. da vil kandidaten bli spurt MCQ og Kodingsspørsmål på det valgte programmeringsspråket.

For å få en følelse av hva slags spørsmål som vil bli bedt om å evaluere ferdigheter i Python eller R, kan du gjennomgå vår standard Python Online Test og r online tester.

Kan jeg evaluere Excel -ferdigheter i Data Analyst -testen?

Ja. Sammen med standard spørsmålssettet vil det være scenariabaserte MCQ-spørsmål for å evaluere Microsoft Excel-opplevelsen på jobben. Du kan gjennomgå vår standard Excel Online Test for å se hvilke spørsmål som skal brukes og hvilke emner som vil bli evaluert.

Kan jeg kombinere flere ferdigheter til en tilpasset vurdering?

Ja absolutt. Tilpassede vurderinger er satt opp basert på stillingsbeskrivelsen din, og vil inneholde spørsmål om alle må-ha ferdigheter du spesifiserer.

Har du noen anti-juksende eller proktoreringsfunksjoner på plass?

Vi har følgende anti-juksede funksjoner på plass:

Ikke-googlable spørsmål
IP Proctoring
Nettproctoring
Webcam Proctoring
Deteksjon av plagiering
Sikker nettleser

Les mer om Proctoring -funksjonene.

Hvordan tolker jeg testresultater?

Den viktigste tingen å huske på er at en vurdering er et eliminasjonsverktøy, ikke et seleksjonsverktøy. En ferdighetsvurdering er optimalisert for å hjelpe deg med å eliminere kandidater som ikke er teknisk kvalifisert for rollen, det er ikke optimalisert for å hjelpe deg med å finne den beste kandidaten for rollen. Så den ideelle måten å bruke en vurdering på er å bestemme en terskelpoeng (vanligvis 55%, vi hjelper deg med å benchmark) og invitere alle kandidater som scorer over terskelen for de neste rundene med intervjuet.

Hvilken opplevelsesnivå kan jeg bruke denne testen til?

Hver ADAFACE -vurdering er tilpasset din stillingsbeskrivelse/ ideell kandidatperson (våre fageksperter vil velge de riktige spørsmålene for din vurdering fra vårt bibliotek med 10000+ spørsmål). Denne vurderingen kan tilpasses for ethvert opplevelsesnivå.

Får hver kandidat de samme spørsmålene?

Ja, det gjør det mye lettere for deg å sammenligne kandidater. Alternativer for MCQ -spørsmål og rekkefølgen på spørsmål er randomisert. Vi har anti-juksing/proctoring funksjoner på plass. I vår bedriftsplan har vi også muligheten til å lage flere versjoner av den samme vurderingen med spørsmål med lignende vanskelighetsnivåer.
