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 ->

🧐 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.

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

Detailed scorecards & benchmarks

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.

FAQ

Quel est le test en ligne SQL Server?

Le test en ligne SQL Server est une évaluation des compétences qui évalue les connaissances et les compétences d'un candidat liées à Microsoft SQL Server, qui est un système de gestion de base de données relationnel utilisé pour stocker et récupérer des données. Le test comprend généralement des questions sur les fonctionnalités du serveur SQL, la conception de la base de données, les requêtes SQL, etc.

Puis-je combiner plusieurs compétences en une seule évaluation personnalisée?

Oui absolument. Les évaluations personnalisées sont configurées en fonction de votre description de poste et comprendront des questions sur toutes les compétences indispensables que vous spécifiez.

Avez-vous en place des fonctionnalités anti-chétion ou de proctorisation?

Nous avons les fonctionnalités anti-modification suivantes en place:

Questions non googléables
IP Proctoring
Proctoring Web
Proctoring webcam
Détection du plagiat
navigateur sécurisé

En savoir plus sur les fonctionnalités de Proctoring.

Comment interpréter les résultats des tests?

La principale chose à garder à l'esprit est qu'une évaluation est un outil d'élimination, pas un outil de sélection. Une évaluation des compétences est optimisée pour vous aider à éliminer les candidats qui ne sont pas techniquement qualifiés pour le rôle, il n'est pas optimisé pour vous aider à trouver le meilleur candidat pour le rôle. Ainsi, la façon idéale d'utiliser une évaluation consiste à décider d'un score de seuil (généralement 55%, nous vous aidons à bencher) et à inviter tous les candidats qui marquent au-dessus du seuil pour les prochains cycles d'entrevue.

Pour quel niveau d'expérience puis-je utiliser ce test?

Chaque évaluation ADAFACE est personnalisée à votre description de poste / Persona de candidats idéaux (nos experts en la matière choisiront les bonnes questions pour votre évaluation de notre bibliothèque de 10000+ questions). Cette évaluation peut être personnalisée pour tout niveau d'expérience.

Chaque candidat reçoit-il les mêmes questions?

Oui, cela vous permet de comparer les candidats. Les options pour les questions du MCQ et l'ordre des questions sont randomisées. Nous avons Anti-Cheating / Proctoring en place. Dans notre plan d'entreprise, nous avons également la possibilité de créer plusieurs versions de la même évaluation avec des questions de niveaux de difficulté similaires.

Je suis candidat. Puis-je essayer un test de pratique?

Non. Malheureusement, nous ne soutenons pas les tests de pratique pour le moment. Cependant, vous pouvez utiliser nos exemples de questions pour la pratique.
