Adaface JavaScript, HTML/CSS, Java & SQL Test is the most accurate way to shortlist Deweloper pełnego stosus

Reason #1

Tests for on-the-job skills

The JavaScript, HTML/CSS, Java & SQL 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:

Możliwość pisania czystego i wydajnego kodu JavaScript
Biegłość w składni i funkcjach ES6
Zrozumienie programowania asynchronicznego i użycie asynchronizacji/oczekiwania w JavaScript
Znajomość podstaw HTML i CSS
Zdolność do manipulowania i interakcji z DOM za pomocą JavaScript
Znajomość składni i koncepcji Java
Zrozumienie obiektowych zasad programowania w Javie
Biegłość w wykonywaniu operacji CRUD w SQL
Możliwość pracy z dołączami i indeksami SQL
Kompetencje w rozwiązywaniu problemów z kodowaniem

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.

We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10

You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment JavaScript, HTML/CSS, Java & SQL 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

What topics are covered in the JavaScript, HTML/CSS, Java & SQL Online Test?

JavaScript Fundamentals
Podstawy JavaScript obejmują podstawowe pojęcia języka programowania JavaScript, w tym zmienne, typy danych, operatory, przepływ kontroli, funkcje i tablice. Ta umiejętność jest mierzona w teście w celu oceny zrozumienia przez kandydata podstawowych pojęć wymaganych do napisania kodu JavaScript.
Składnia ES6
Składnia ES6 odnosi się do funkcji wprowadzonych w standardowym standardzie EcMascript 6 , takie jak funkcje strzałek, literały szablonów, rozpowszechnianie składni i przypisanie destrukcyjne. Ocena tej umiejętności pomaga ocenić znajomość kandydata w nowoczesnej składni JavaScript, a jego zdolność do korzystania z zaawansowanych funkcji języka.
Async/Oczekiwanie w JS
Async/Akacie jest zestawem słów kluczowych w JavaScript w JavaScript To pozwalają na czystszy i bardziej ekspresyjny kod asynchroniczny poprzez uproszczenie obsługi obietnic. Ta umiejętność jest ważna do pomiaru, ponieważ wskazuje biegłość kandydata w pisaniu wydajny i elegancki asynchroniczny kod JavaScript.
HTML/CSS Podstawy
HTML/CSS Podstawy obejmują zrozumienie podstawowych budownictwa budowlanego Building of Building of Building of Building of Building of Building Web - HTML, która zapewnia strukturę i CSS, która umożliwia stylizację wizualną. Ocena tej umiejętności pomaga określić zrozumienie podstawowych pojęć i składni wymaganych do tworzenia i stylu stron internetowych.
Dom obsługuje JS
DOM (model Dokument Object) z JS Refers do manipulacji i interakcji ze strukturą dokumentu HTML za pomocą JavaScript. Ta umiejętność jest mierzona w teście, aby ocenić zdolność kandydata do dynamicznej modyfikowania treści strony internetowej i reagowania na interakcje użytkownika.
Java Składnia
Składnia Java obejmuje składnię i podstawowe pojęcia Język programowania Java, w tym zmienne, typy danych, operatory, przepływ kontroli i metody. Ocena tej umiejętności pomaga ustalić zrozumienie kandydata podstawowych elementów programowania Java.
Java Oops
Java OOPS (programowanie obiektowe) obejmuje pojęcia takie jak dziedziczenie, enkapsulacja, polimorfizm, i abstrakcja, która jest fundamentalna dla rozwoju Java. Ta umiejętność jest mierzona w teście w celu oceny biegłości kandydata w stosowaniu zasad obiektowych w celu opracowania wydajnego i możliwego do utrzymania kodu Java.
SQL CRUD Operations
SQL CRUD (Utwórz, czytaj, Aktualizacja, Usuń) Operacje odnoszą się do podstawowych operacji bazy danych w celu manipulowania danymi w relacyjnej bazie danych przy użyciu zapytań SQL. Ocena tej umiejętności pomaga ocenić zdolność kandydata do interakcji z bazami danych i wykonywać niezbędne zadania manipulacji danymi.
SQL Złącza i indeksy
SQL Złącza i indeksy obejmują techniki w SQL w celu połączenia danych z wielu danych z wielu danych z wielu danych z wielu danych z wielu danych z wielu danych Tabele przy użyciu klauzul łączących i optymalizację wydajności zapytania za pomocą indeksów. Ta umiejętność jest ważna do pomiaru, ponieważ pokazuje zrozumienie kandydata zaawansowanych koncepcji SQL w celu skutecznego wyszukiwania i manipulacji 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.

Do jakiego poziomu doświadczenia mogę użyć tego testu?

Każda ocena Adaface jest dostosowana do opisu stanowiska/ idealnego kandydującego osobowości (nasi eksperci przedmiotu będą podejmować właściwe pytania dotyczące oceny z naszej biblioteki ponad 10000 pytań). Ocenę tę można dostosować do dowolnego poziomu doświadczenia.

Czy każdy kandydat otrzymuje te same pytania?

Tak, znacznie ułatwia porównanie kandydatów. Opcje pytań MCQ i kolejność pytań są losowe. Mamy funkcje anty-cheating/proctoring. W naszym planie korporacyjnym mamy również możliwość tworzenia wielu wersji tej samej oceny z pytaniami o podobnych poziomach trudności.
