9 reasons why

Adaface Java & Android Test is the most accurate way to shortlist desenvolvedor de Javas

Reason #1

Tests for on-the-job skills

The Java & Android 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:

Capaz de escrever código Java usando sintaxe básica e tipos de dados
Proficiente em conceitos de programação orientados a objetos em Java
Conhecimento na estrutura de coleções Java e estruturas de dados
Familiarizado com a estrutura principal do desenvolvimento do Android
Capaz de projetar e implementar componentes Android
Qualificado no manuseio de interações do usuário do Android
Capaz de lidar com exceções e erros com eficiência em Java
Experiente na utilização de princípios de codificação Java e práticas recomendadas

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 pass a value to next activity in Android. Which of the following options are the right way to do it?
Easy Linear Layout	Try practice test
Check the following XML layout file. What will the UI for this layout file look like? 1. An edit text to the right of a text view and a button beneath them 2. An edit text to the right of a text view and a button to the right of the text view 3. A text view, an edit text beneath it and the button beneath the edit text 4. An edit text to the left of a text view and a button beneath it
Easy Registration Queue Logic Queues	Solve
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
Medium Visitors Count Strings Logic	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. 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 Teste Java e Android 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.

What topics are covered in the Java & Android Online Test?

java oops
java oops (objeto- Programação orientada) envolve a compreensão dos princípios de encapsulamento, herança, polimorfismo e abstração em Java. Essa habilidade permite que os desenvolvedores escrevam código modular, sustentável e reutilizável. É importante avaliar essa habilidade no teste para avaliar a capacidade de um candidato de implementar soluções Java eficientes e escaláveis. Estruturas de dados, como listas, conjuntos e mapas. É essencial que os desenvolvedores sejam proficientes nessa habilidade para manipular e armazenar dados de maneira eficaz. Avaliar essa habilidade no teste permite que os recrutadores avaliem a proficiência de um candidato no uso dessas estruturas de dados para resolver problemas do mundo real. Classes e bibliotecas essenciais que facilitam o desenvolvimento de aplicativos Android. Inclui componentes como Atividade, Serviço, ContentProvider e Intent. Medir essa habilidade no teste ajuda os recrutadores a avaliar a compreensão de um candidato dos principais blocos de construção de aplicações do Android. atividades, fragmentos e vistas. Essa habilidade é importante para avaliar no teste, pois demonstra a capacidade de um candidato de projetar e estruturar a interface do usuário e a funcionalidade de um aplicativo Android. O manuseio envolve capturar e responder às ações do usuário em um aplicativo Android, como cliques de botão, gestos e eventos de toque. É crucial avaliar essa habilidade no teste para garantir que os candidatos possam criar experiências intuitivas e responsivas do usuário em seus aplicativos Android.

Java & Android Hiring Test Perguntas frequentes

Posso combinar várias habilidades em uma avaliação personalizada?

Sim absolutamente. As avaliações personalizadas são configuradas com base na descrição do seu trabalho e incluirão perguntas sobre todas as habilidades obrigatórias que você especificar.

Você tem algum recurso anti-trapaça ou procurador?

Temos os seguintes recursos anti-trapaça:

Perguntas não-goleadas

Como interpreto as pontuações dos testes?

O principal a ter em mente é que uma avaliação é uma ferramenta de eliminação, não uma ferramenta de seleção. Uma avaliação de habilidades é otimizada para ajudá -lo a eliminar os candidatos que não são tecnicamente qualificados para o papel, não é otimizado para ajudá -lo a encontrar o melhor candidato para o papel. Portanto, a maneira ideal de usar uma avaliação é decidir uma pontuação limite (normalmente 55%, ajudamos você a comparar) e convidar todos os candidatos que pontuam acima do limiar para as próximas rodadas da entrevista.

Para que nível de experiência posso usar este teste?

Cada avaliação do Adaface é personalizada para a descrição do seu trabalho/ persona do candidato ideal (nossos especialistas no assunto escolherão as perguntas certas para sua avaliação de nossa biblioteca de mais de 10000 perguntas). Esta avaliação pode ser personalizada para qualquer nível de experiência.

Todo candidato recebe as mesmas perguntas?

Sim, facilita muito a comparação de candidatos. As opções para perguntas do MCQ e a ordem das perguntas são randomizadas. Recursos anti-traking/proctoring no local. Em nosso plano corporativo, também temos a opção de criar várias versões da mesma avaliação com questões de níveis de dificuldade semelhantes.
