Medium Data Merging Data Merging Conditional Logic	Try practice test
A data engineer is tasked with merging and transforming data from two sources for a business analytics report. Source 1 is a SQL database 'Employee' with fields EmployeeID (int), Name (varchar), DepartmentID (int), and JoinDate (date). Source 2 is a CSV file 'Department' with fields DepartmentID (int), DepartmentName (varchar), and Budget (float). The objective is to create a summary table that lists EmployeeID, Name, DepartmentName, and YearsInCompany. The YearsInCompany should be calculated based on the JoinDate and the current date, rounded down to the nearest whole number. Consider the following initial SQL query: Which of the following modifications ensures accurate data transformation as per the requirements? A: Change FLOOR to CEILING in the calculation of YearsInCompany. B: Add WHERE e.JoinDate IS NOT NULL before the JOIN clause. C: Replace JOIN with LEFT JOIN and use COALESCE(d.DepartmentName, 'Unknown'). D: Change the YearsInCompany calculation to YEAR(CURRENT_DATE) - YEAR(e.JoinDate). E: Use DATEDIFF(YEAR, e.JoinDate, CURRENT_DATE) for YearsInCompany calculation.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Test de Sybase IQ 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.

La mesure de cette compétence dans le test aide à évaluer la compréhension des candidats des principes d'entreposage des données et de leur capacité à concevoir et à gérer les entrepôts de données.
Analyse des données
L'analyse de données implique le processus d'examen de grands volumes de données pour découvrir les modèles, les tendances et les informations qui peuvent être utilisées pour prendre des décisions commerciales éclairées. Il englobe des tâches telles que l'exploration de données, la visualisation des données, la modélisation prédictive et l'analyse statistique. Tester les compétences d'analyse des données des candidats aide à évaluer leur capacité à analyser et à interpréter efficacement les données en utilisant des techniques et des outils appropriés.
Optimisation des requêtes
L'optimisation des requêtes est le processus d'amélioration des performances des requêtes de base de données en sélectionnant le plan d'exécution le plus efficace. Il implique des techniques telles que l'optimisation de l'index, la réécriture de la requête et le réglage de la base de données pour réduire le temps d'exécution des requêtes et la consommation de ressources. La mesure de cette compétence dans le test aide à évaluer la capacité des candidats à optimiser les requêtes et à améliorer les performances globales de la base de données.
Modélisation des données
La modélisation des données est le processus de création d'une représentation logique des structures de données Dans une base de données. Il s'agit de définir des entités, des attributs, des relations et des contraintes pour assurer l'intégrité et la précision des données. Tester les compétences de modélisation des données des candidats aide à évaluer leur capacité à concevoir des bases de données efficaces et bien structurées qui répondent aux exigences de l'organisation.
ETL (Extract, Transform, Load)
ETL fait référence Aux processus impliqués dans l'extraction de données de diverses sources, en les transformant en un format cohérent et en les chargeant en une base de données cible ou un entrepôt de données. Il comprend des tâches telles que le nettoyage des données, l'intégration des données et la validation des données. L'évaluation de la maîtrise des candidats dans l'ETL dans le test aide à déterminer leur capacité à gérer efficacement les complexités de l'extraction, de la transformation et du chargement de données.
Le réglage des performances de la base de données
Le réglage des performances de la base de données implique l'optimisation du Performances d'un système de base de données en ajustant divers paramètres, configurations et conceptions de bases de données. Il vise à améliorer la vitesse d'exécution des requêtes, à améliorer la récupération des données et l'efficacité de stockage et à réduire les goulots d'étranglement du système. La mesure de cette compétence dans le test aide à évaluer la capacité des candidats à identifier et à résoudre les problèmes de performance et à optimiser les performances globales de la base de données.

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.
