9 reasons why

Adaface MySQL Online Test is the most accurate way to shortlist MySQL Developers

Reason #1

Tests for on-the-job skills

MySQL er et relationel databasestyringssystem baseret på SQL - struktureret forespørgselssprog. Applikationen bruges til en lang række formål, herunder datalagring, e-handel og logging af applikationer. Den mest almindelige anvendelse til MySQL er imidlertid med henblik på en webdatabase.

Med tilgængeligheden af omfattende dokumentation er det at udvikle en applikation omkring MySQL noget, som mange udviklere kender MySQL. At styre MySQL -forekomster, mens de sikrer, at deres ydeevne, tilgængelighed og sikkerhed er noget, kun kompetent og ansvarlige MySQL -databaseadministratorer kan gøre med elegance.

Typisk ansvar for en MySQL -udvikler inkluderer:

Konstruktion af MySQL -databasen og vedligeholdelse af den
Bestem, hvordan data skal organiseres, hvem der skal have adgang til forskellige data, og hvordan de skal vises
Hjælp udviklere med at optimere forespørgsler, lagret procedure og databasedesign
Design og udvikle datamodeller og databasearkitektur
Håndter almindelige databaseprocedurer, såsom opgradering, backup, gendannelse, migration osv.
Forbered rapporter til databaser og tilpas dem til specifikke behov
Giv træning til brugere af systemet og yder teknisk support om nødvendigt

Testen er designet til at filtrere kandidater til roller som:

Database Administrator
MySQL -udvikler
Systemadministrator
DevOps Engineer
Software ingeniør

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.

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.

Why we started Adaface ->

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.

Dette er kun en lille prøve fra vores bibliotek med 10.000+ spørgsmål. De faktiske spørgsmål om dette MySQL Online Test vil være ikke-gåbart.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment MySQL Online 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the MySQL Online 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.

Reason #7

Detailed scorecards & comparative results

Reason #8

High completion rate

Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

De ansættelsesledere mente, at de gennem de tekniske spørgsmål, som de stillede under panelinterviewene, kunne fortælle, hvilke kandidater der havde bedre scoringer, og differentierede med dem, der ikke scorede så godt. De er meget tilfreds med kvaliteten af kandidater, der er på listen med Adaface -screeningen.

FAQS

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

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.
