9 reasons why

Adaface Probability Assessment Test is the most accurate way to shortlist Data -analists

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:

Inzicht in basiskansconcepten
Mogelijkheid om combinatorische technieken toe te passen in waarschijnlijkheidsproblemen
Kennis van willekeurige variabelen en hun eigenschappen
Inzicht in gezamenlijke kansverdelingen
Kwantitatieve aanleg voor het oplossen van waarschijnlijkheidsgerelateerde problemen
Mogelijkheid om numeriek te redeneren in waarschijnlijkheidsscenario's

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	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 Waarschijnlijkheidstest 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.

Inzicht in gezamenlijke distributies
Kwantitatieve aanlegvaardigheden
Numeriek redeneervermogen
Solid greep van waarschijnlijkheidsfunderingen

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the Probability Test?

combinatorics </h4> <P > Combinatorics is de vaardigheid van het tellen en regelen van objecten of gebeurtenissen. Het omvat concepten zoals permutaties, combinaties en de principes van tellen. Het meten van deze vaardigheid in de test helpt bij het evalueren van het vermogen van de kandidaat om problemen op te lossen met betrekking tot het regelen, selecteren en tellen Vaardigheid van willekeurige variabelen omvat het begrijpen van het concept van willekeurige variabelen en hun waarschijnlijkheidsverdelingen. Willekeurige variabelen zijn variabelen waarvan de waarden afhankelijk zijn van de uitkomst van een willekeurige gebeurtenis. Het meten van deze vaardigheid in de test kan het vermogen van de kandidaat beoordelen om willekeurige fenomenen te analyseren en te interpreteren, en waarschijnlijkheidsverdelingen toe te passen op het modelleren van real-world situaties. </p> <h4> gezamenlijke distributies
Gezamenlijke verdeling verwijzen verwijzen naar de waarschijnlijkheidsverdeling van twee of meer willekeurige variabelen. Deze vaardigheid omvat het begrijpen van de gezamenlijke waarschijnlijkheidsverdeling, voorwaardelijke waarschijnlijkheid en gerelateerde concepten. Het opnemen van deze vaardigheid in de test helpt bij het evalueren van de greep van de kandidaat bij het modelleren en analyseren van de relaties tussen meerdere willekeurige variabelen, wat essentieel is op verschillende gebieden zoals machine learning, financiën en operationele onderzoek.

Probability Hiring Test Veelgestelde vragen

Kan ik meerdere vaardigheden combineren in één aangepaste beoordeling?

Ja absoluut. Aangepaste beoordelingen zijn opgezet op basis van uw functiebeschrijving en bevatten vragen over alle must-have vaardigheden die u opgeeft.

Heeft u functies tegen latere of proctoring op hun plaats?

We hebben de volgende anti-cheating-functies op zijn plaats:

Niet-googelbare vragen
IP Proctoring
Web Proctoring
Webcam Proctoring
Plagiaatdetectie
Beveilig browser

Lees meer over de Proctoring -functies.

Hoe interpreteer ik testscores?

Het belangrijkste om in gedachten te houden is dat een beoordeling een eliminatietool is, geen selectietool. Een vaardighedenbeoordeling is geoptimaliseerd om u te helpen kandidaten te elimineren die niet technisch gekwalificeerd zijn voor de rol, het is niet geoptimaliseerd om u te helpen de beste kandidaat voor de rol te vinden. Dus de ideale manier om een beoordeling te gebruiken is om een drempelscore te bepalen (meestal 55%, wij helpen u benchmark) en alle kandidaten uit te nodigen die boven de drempel scoren voor de volgende interviewrondes.

Voor welk ervaringsniveau kan ik deze test gebruiken?

Elke ADAFACE -beoordeling is aangepast aan uw functiebeschrijving/ ideale kandidaatpersonage (onze experts van het onderwerp zullen de juiste vragen kiezen voor uw beoordeling uit onze bibliotheek van 10000+ vragen). Deze beoordeling kan worden aangepast voor elk ervaringsniveau.

Krijgt elke kandidaat dezelfde vragen?

Ja, het maakt het veel gemakkelijker voor u om kandidaten te vergelijken. Opties voor MCQ -vragen en de volgorde van vragen worden gerandomiseerd. We hebben anti-cheating/proctoring functies. In ons bedrijfsplan hebben we ook de optie om meerdere versies van dezelfde beoordeling te maken met vragen over vergelijkbare moeilijkheidsniveaus.
