9 reasons why

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

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:

Comprensión de los conceptos de probabilidad básicos
Capacidad para aplicar técnicas combinatorias en problemas de probabilidad
Conocimiento de variables aleatorias y sus propiedades
Comprensión de las distribuciones de probabilidad conjunta
Aptitud cuantitativa para resolver problemas relacionados con la probabilidad
Capacidad para razonar numéricamente en escenarios de probabilidad

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.

Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

🧐 Question
Medium Green or red balls	Solve
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	Solve
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	Solve
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	Solve
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	Solve
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 Prueba de probabilidad 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 Prueba de probabilidad 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.

Probability Hiring Test Preguntas frecuentes

¿Puedo combinar múltiples habilidades en una evaluación personalizada?

Si, absolutamente. Las evaluaciones personalizadas se configuran en función de la descripción de su trabajo e incluirán preguntas sobre todas las habilidades imprescindibles que especifique.

¿Tiene alguna característica anti-trato o procuración en su lugar?

Tenemos las siguientes características anti-trate en su lugar:

Preguntas no postradas
Procuración de IP
Procedor web
Procedores de cámara web
Detección de plagio
navegador seguro

Lea más sobre las funciones de procuración.

¿Cómo interpreto los puntajes de las pruebas?

Lo principal a tener en cuenta es que una evaluación es una herramienta de eliminación, no una herramienta de selección. Una evaluación de habilidades está optimizada para ayudarlo a eliminar a los candidatos que no están técnicamente calificados para el rol, no está optimizado para ayudarlo a encontrar el mejor candidato para el papel. Por lo tanto, la forma ideal de usar una evaluación es decidir un puntaje umbral (generalmente del 55%, lo ayudamos a comparar) e invitar a todos los candidatos que obtienen un puntaje por encima del umbral para las próximas rondas de la entrevista.

¿Para qué nivel de experiencia puedo usar esta prueba?

Cada evaluación de AdaFace está personalizada para su descripción de trabajo/ persona candidata ideal (nuestros expertos en la materia elegirán las preguntas correctas para su evaluación de nuestra biblioteca de más de 10000 preguntas). Esta evaluación se puede personalizar para cualquier nivel de experiencia.

¿Cada candidato tiene las mismas preguntas?

Sí, te hace mucho más fácil comparar los candidatos. Las opciones para las preguntas de MCQ y el orden de las preguntas son aleatorizados. Tenemos características anti-trato/procuración en su lugar. En nuestro plan empresarial, también tenemos la opción de crear múltiples versiones de la misma evaluación con cuestiones de niveles de dificultad similares.
