9 reasons why

Adaface Probability Assessment Test is the most accurate way to shortlist Analista de informaçõess

Reason #1

Tests for on-the-job skills

The Probability 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:

Entendimento dos conceitos de probabilidade básica
Capacidade de aplicar técnicas combinatórias em problemas de probabilidade
Conhecimento de variáveis aleatórias e suas propriedades
Compreensão das distribuições de probabilidade conjunta
Aptidão quantitativa para resolver problemas relacionados à probabilidade
Capacidade de raciocinar numericamente em cenários de probabilidade

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.

🧐 Question
Medium Green or red balls	Try practice test
A bag contains 5 red balls, 6 yellow balls and 3 green balls. If two balls are picked at random, what is the probability that both are red or both are green in colour?
Hard Square points and Circle	Try practice test
What is the probability that two uniformly random points in the square are such that center of the square lies in the circle formed by taking the points as diameter
Medium Increasing monthly gross profit Percentage Calculations	Try practice test
The CEO of Snipr. Inc wants to grow monthly gross profit by 4%. If costs stay the same, what does the sales turnover need to be in February to achieve this goal?
Hard Magic bag Arithmetic Sequences	Try practice test
Alex’s uncle is a magician who gave them a magic bag in which coins get doubled each time you put those coins into it. Initially, Alex had few coins with them. So, Alex put all the coins, and the coins got doubled. Alex took out all the coins and gave a few to their friend and then again put the remaining coins back in the bag. The coins doubled again; Alex took out all the coins again and gave a few coins to their second friend. Alex then put the remaining coins in the bag and the coins doubled again. Alex took out all the coins and gave a few coins to their third friend. There were no coins left with Alex when Alex gave coins to the third friend and Alex gave an equal number of coins to each friend. What is the minimum number of coins Alex had initially and how much did Alex give to each friend? A: Started with 3 coins B: Started with 5 coins C: Started with 6 coins D: Started with 7 coins E: Started with 9 coins F: Gave 3 coins in every turn G: Gave 4 coins in every turn H: Gave 5 coins in every turn I: Gave 7 coins in every turn J: Gave 8 coins in every turn K: Gave 9 coins in every turn
Medium Three Clocks Time Calculations	Try practice test
In my house, there are three clocks of different shapes – a round clock, a square clock, and a rhombus clock. The rhombus clock is always accurate whereas the round clock gains 2 minutes every day and the square clock loses 2 minutes every day. I checked the clocks on July 22nd, 2007 at 10 PM, and they were showing different times. Two hours later, when I checked, the clocks were showing the same time, then on which date will all three clocks show the same time again?

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Teste de probabilidade 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.

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?
