9 reasons why

Adaface SQL Server Test is the most accurate way to shortlist Database Administrators

Reason #1

Tests for on-the-job skills

The SQL Server Online 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:

Evne til at designe og implementere transaktions- og relationelle databaser
Evne til at konfigurere SQL -serverindstillinger og optimeringer
Evne til at oprette og administrere databaseobjekter
Evne til at installere SQL Server og udføre nødvendige konfigurationer
Evne til at synkronisere data mellem flere databaser
Evne til at administrere transaktionslogfiler effektivt
Evne til at overvåge og vedligeholde databaser
Evne til at sikkerhedskopiere og gendanne databaser
Evne til fejlfinding af SQL Server -databasesikkerhedsproblemer
Evne til at arbejde med Storage Area Network (SAN)

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.

🧐 Question
Medium Backup Strategy Backups Troubleshooting	Try practice test
As a DBA, you receive an alert notifying you that the production database has gone offline due to a severe issue. Fortunately, you have a proper backup strategy in place. The backups are performed as follows: 1. Full database backup every Sunday at 2:00 AM. 2. Differential backup every day at 2:00 AM, except Sunday. 3. Transaction log backup every hour. Today is Wednesday, and the failure occurred at 10:15 AM. You have the following backup files available: 1. Full backup: Full_Backup_Sun.bak taken on Sunday 2:00 AM. 2. Differential backups: Diff_Backup_Mon.bak, Diff_Backup_Tue.bak, Diff_Backup_Wed.bak taken at 2:00 AM on their respective days. 3. Transaction log backups: Hourly backups from Sunday 3:00 AM until Wednesday 10:00 AM, like TLog_Backup_Wed_09.bak, TLog_Backup_Wed_10.bak. Given the RPO (Recovery Point Objective) of 15 minutes, which of the following sequences of restore operations would ensure minimal data loss? A: Full_Backup_Sun.bak, Diff_Backup_Wed.bak, then all Transaction Log backups from Wednesday. B: Full_Backup_Sun.bak, Diff_Backup_Tue.bak, then all Transaction Log backups from Tuesday and Wednesday. C: Full_Backup_Sun.bak, Diff_Backup_Wed.bak, then Transaction Log backups from Wednesday 2:00 AM to 10:00 AM. D: Full_Backup_Sun.bak, then all Transaction Log backups from Sunday to Wednesday 10:00 AM.

Medium Optimizing Query Performance Indexing Join Optimization Execution Plans	Try practice test
You are managing a SQL Server database for a large e-commerce platform. The database contains the following tables: Users often run a query to retrieve all orders from a specific date along with customer details and a breakdown of each order. Lately, this query has been performing poorly, especially on days with a high volume of orders. Given this schema, which of the following changes would MOST LIKELY enhance the performance of this query? A: Create a non-clustered index on Orders(OrderDate, OrderID) and a clustered index on OrderDetails(OrderID). B: Create a clustered index on Orders(CustomerID, OrderDate) and a non-clustered index on OrderDetails(ProductName).

D: Create a clustered index on Orders(OrderDate) and a non-clustered index on OrderDetails(OrderID, Quantity). E: Partition the Orders table on OrderDate and create a non-clustered index on OrderDetails(DetailID, Price).
Medium Transaction Isolation Transaction Isolation Levels Snapshot Isolation	Try practice test
You are managing a SQL Server instance that is experiencing performance degradation. After some analysis, you realize that the TempDB is under heavy stress due to numerous long-running transactions. Users have reported that some SELECT queries on a large table, named SalesData, are slower than expected. You consider implementing Snapshot Isolation to mitigate blocking issues. You're aware that Snapshot Isolation uses TempDB to store row versions. Given the situation, which combination of actions will help alleviate the stress on TempDB and enhance the performance of SELECT queries on SalesData? A: Move TempDB to a faster storage subsystem and enable Snapshot Isolation for SalesData. B: Increase the number of TempDB data files, shrink TempDB size, and enable Snapshot Isolation for the database. C: Implement Read Committed Snapshot Isolation (RCSI) for the database and partition the SalesData table. D: Reduce the TempDB size, implement table partitioning on SalesData, and enable Read Uncommitted isolation level for the SELECT queries. E: Create a non-clustered index on frequently queried columns of SalesData and enable row versioning for the entire database.
Medium Transaction Log Management Performance Tuning Log Management is-not-mysql	Try practice test
You are a DBA at a large company managing an SQL Server database which is crucial for daily operations. The database is configured with the Full recovery model.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment SQL Server 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

SQL Server Hiring Test Ofte stillede spørgsmål

Hvad er SQL Server Online -testen?

SQL Server Online Test er en færdighedsvurdering, der evaluerer en kandidats viden og færdigheder relateret til Microsoft SQL Server, som er et relationel databasestyringssystem, der bruges til lagring og hentning af data. Testen inkluderer typisk spørgsmål på SQL Server -funktioner, databasedesign, SQL -forespørgsler osv.

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.
