Medium Data Merging Data Merging Conditional Logic	Solve
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.

Medium Normalization Process Normalization Database Design Anomaly Elimination	Solve
Consider a healthcare database with a table named PatientRecords that stores patient visit information.

Reason #5

Designed for elimination, not selection

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

Science behind Adaface tests

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Test Sybase IQ 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.

What topics are covered in the Sybase IQ Test?

Sybase IQ
Sybase IQ to system zarządzania bazą danych zorientowany na kolumnę, masowo przetwarzanie równolegle (MPP) zaprojektowany do obciążeń internetowych przetwarzania analitycznego (OLAP). Zapewnia zaawansowane możliwości analityczne, wysokowydajne wykonywanie SQL i wydajną kompresję danych. Ta umiejętność jest mierzona w teście, aby ocenić biegłość kandydatów w pracy z SYBase IQ i wykonywanie zadań analizy danych.
Zarządzanie bazą danych
Zarządzanie bazami danych pociąga za sobą administrację, organizację i utrzymanie bazy danych organizacji. Obejmuje zadania, takie jak tworzenie i zarządzanie schematami bazy danych, zapewnienie integralności danych, optymalizację wydajności bazy danych i wdrażanie środków bezpieczeństwa. Mierzenie tej umiejętności w teście pomaga ocenić zdolność kandydatów do skutecznego obsługi zadań związanych z bazą danych.
SQL
Structud Query Language (SQL) jest językiem programowania używanym do zarządzania i manipulowania relacyjnymi bazy danych. Pozwala użytkownikom wykonywać różne operacje, takie jak zapytania, wkładanie, aktualizowanie i usuwanie rekordów, tworzenie i modyfikowanie schematów bazy danych oraz optymalizację wydajności bazy danych. Ocena umiejętności SQL kandydatów w teście pomaga określić ich biegłość w pracy z bazami danych.
Hurtowni danych
Warehousing danych obejmuje proces gromadzenia, przechowywania i organizowania dużych ilości struktury i Nieustrukturyzowane dane z różnych źródeł w celu wspierania inteligencji biznesowej i raportowania. Obejmuje zadania, takie jak ekstrakcja danych, transformacja i ładowanie (ETL), modelowanie danych i wdrażanie hurtowni danych do wydajnej analizy danych. Mierzenie tej umiejętności w teście pomaga ocenić zrozumienie przez kandydatów zasad magazynowania danych oraz ich zdolność do projektowania i zarządzania magazynami danych.
Analityka danych

Jak interpretować wyniki testów?

Najważniejsze, o czym należy pamiętać, jest to, że ocena jest narzędziem eliminacyjnym, a nie narzędziem wyboru. Ocena umiejętności jest zoptymalizowana, aby pomóc Ci wyeliminować kandydatów, którzy nie są technicznie zakwalifikowani do roli, nie jest zoptymalizowana, aby pomóc Ci znaleźć najlepszego kandydata do tej roli. Dlatego idealnym sposobem na wykorzystanie oceny jest podjęcie decyzji o wyniku progowym (zwykle 55%, pomagamy Ci porównać) i zaprosić wszystkich kandydatów, którzy wyniki powyżej progu na następne rundy wywiadu.
