9 reasons why

Adaface SQL Server Online Test is the most accurate way to shortlist SQL Server DBAs

Reason #1

Tests for on-the-job skills

De vragen voor senior kandidaten beoordelen geavanceerde onderwerpen zoals:

** Query -optimalisatie **: vragen evalueren het vermogen van de kandidaat om query's te optimaliseren met behulp van indexering, partitionering en andere technieken. Deze vaardigheid is essentieel voor het verbeteren van de databaseprestaties en schaalbaarheid.
** Database -ontwerp **: kandidaten worden verwacht dat ze bekwaam zijn in databaseontwerp, normalisatie en schema -ontwerp. Deze kennis is cruciaal voor het ontwerpen van efficiënte en onderhoudbare databases.
** opgeslagen procedures en functies **: Vragen beoordelen het vermogen van de kandidaat om efficiënte en herbruikbare opgeslagen procedures en functies te schrijven. Deze vaardigheid is belangrijk voor het verminderen van de hoeveelheid overbodige code en het verbeteren van de databaseprestaties.
** Transacties en vergrendeling **: Kandidaten worden geëvalueerd op hun begrip van transacties, isolatieniveaus en vergrendelingsmechanismen. Deze kennis is essentieel voor het waarborgen van gegevensintegriteit en het voorkomen van gelijktijdigheidsproblemen.
** Performance tuning **: vragen evalueren het vermogen van de kandidaat om prestatieproblemen in SQL Server te diagnosticeren en op te lossen. Deze vaardigheid is belangrijk om ervoor te zorgen dat databases grote hoeveelheden gegevens en hoog gebruikersverkeer kunnen verwerken.
** Hoge beschikbaarheid en noodherstel **: Kandidaten zullen naar verwachting bedreven zijn in het configureren van hoge beschikbaarheid en oplossingen voor noodherstel zoals clustering, replicatie en back -up/herstel. Deze kennis is essentieel om ervoor te zorgen dat kritieke databases altijd beschikbaar zijn en beschermd tegen gegevensverlies.
** Beveiliging en compliance **: Vragen beoordelen het begrip van de kandidaat van SQL Server -beveiligingsfuncties en compliance -voorschriften zoals GDPR en HIPAA. Deze kennis is belangrijk om ervoor te zorgen dat databases veilig en voldoen aan de wettelijke en wettelijke vereisten.
** Business Intelligence **: Kandidaten worden geëvalueerd op hun vermogen om oplossingen voor business intelligence te ontwerpen en te ontwikkelen met behulp van SQL Server -tools zoals analyseservices, integratiediensten en rapportageservices. Deze kennis is belangrijk voor het bieden van inzichten en gegevensgestuurde besluitvorming.
** ETL -processen **: vragen evalueren het vermogen van de kandidaat om extract, transformatie, laad (ETL) processen te ontwerpen en te implementeren met behulp van SQL Server Integration Services. Deze vaardigheid is belangrijk voor het integreren van gegevens uit verschillende bronnen en het omzetten in bruikbare informatie.
** Data Warehousing **: Kandidaten zullen naar verwachting bedreven zijn in het ontwerpen en implementeren van datawarehousing -oplossingen met behulp van SQL Server -tools zoals analyseservices en integratiediensten. Deze kennis is belangrijk voor het bieden van een centrale repository voor grote hoeveelheden gegevens en het inschakelen van gegevensanalyse en rapportage.

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.

These are just a small sample from our library of 10,000+ questions. The actual questions on this Microsoft SQL Server Test will be non-googleable.

🧐 Question
Medium Backup Strategy Backups Troubleshooting	Solve
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. E: Full_Backup_Sun.bak, Diff_Backup_Mon.bak, Diff_Backup_Tue.bak, Diff_Backup_Wed.bak, then Transaction Log backups from Wednesday 2:00 AM to 10:00 AM.
Medium Transaction Log Management Performance Tuning Log Management	Solve
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. The database is experiencing considerable transaction log growth during business hours, which is impacting the disk space and performance. The following operations are performed on this database: 1. A large ETL process that runs every night, which transforms and loads data into several tables. 2. A data archiving job that runs every night, which removes old data from several tables. 3. Frequent read/write operations during the day as part of normal business operations. Given this scenario, which of the following strategies could help manage the transaction log growth effectively? A: Switch to the Simple recovery model. B: Schedule frequent log backup and cleanups during business hours. C: Shrink the transaction log file size during business hours. D: Increase the database file size.
Medium Multi Select	Solve
Consider the following SQL table: How many rows does the following SQL query return?
Medium Select & IN	Solve
Consider the following SQL table: Which of the following SQL queries would return the year when neither a football or cricket winner was chosen?
Hard With, AVG & SUM	Solve
Consider the following SQL table: How many tuples does the following query return?

Reason #4

1200+ customers in 75 countries

With Adaface, we were able to optimise our initial screening process by upwards of 75%, freeing up precious time for both hiring managers and our talent acquisition team alike!

Brandon Lee, Head of People, Love, Bonito

Reason #5

Designed for elimination, not selection

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

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Microsoft SQL Server 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

FAQs

Wat is de SQL Server Online -test?

De SQL Server Online -test is een vaardighedenbeoordeling die de kennis en vaardigheden van een kandidaat evalueert met betrekking tot Microsoft SQL Server, een relationeel databasebeheersysteem dat wordt gebruikt voor het opslaan en ophalen van gegevens. De test bevat meestal vragen over SQL Server -functies, database -ontwerp, SQL -query's enz.

Kan ik meerdere vaardigheden combineren in één aangepaste beoordeling?

Ja absoluut. Aangepaste beoordelingen zijn opgezet op basis van uw functiebeschrijving en bevatten vragen over alle must-have vaardigheden die u opgeeft.

Heeft u functies tegen latere of proctoring op hun plaats?

We hebben de volgende anti-cheating-functies op zijn plaats:

Niet-googelbare vragen
IP Proctoring
Web Proctoring
Webcam Proctoring
Plagiaatdetectie
Beveilig browser

Lees meer over de Proctoring -functies.

Hoe interpreteer ik testscores?

Het belangrijkste om in gedachten te houden is dat een beoordeling een eliminatietool is, geen selectietool. Een vaardighedenbeoordeling is geoptimaliseerd om u te helpen kandidaten te elimineren die niet technisch gekwalificeerd zijn voor de rol, het is niet geoptimaliseerd om u te helpen de beste kandidaat voor de rol te vinden. Dus de ideale manier om een beoordeling te gebruiken is om een drempelscore te bepalen (meestal 55%, wij helpen u benchmark) en alle kandidaten uit te nodigen die boven de drempel scoren voor de volgende interviewrondes.

Voor welk ervaringsniveau kan ik deze test gebruiken?

Elke ADAFACE -beoordeling is aangepast aan uw functiebeschrijving/ ideale kandidaatpersonage (onze experts van het onderwerp zullen de juiste vragen kiezen voor uw beoordeling uit onze bibliotheek van 10000+ vragen). Deze beoordeling kan worden aangepast voor elk ervaringsniveau.

Krijgt elke kandidaat dezelfde vragen?

Ja, het maakt het veel gemakkelijker voor u om kandidaten te vergelijken. Opties voor MCQ -vragen en de volgorde van vragen worden gerandomiseerd. We hebben anti-cheating/proctoring functies. In ons bedrijfsplan hebben we ook de optie om meerdere versies van dezelfde beoordeling te maken met vragen over vergelijkbare moeilijkheidsniveaus.
