9 reasons why

Adaface Probability Assessment Test is the most accurate way to shortlist Dataanalytikers

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:

Forståelse af grundlæggende sandsynlighedskoncepter
Evne til at anvende kombinatoriske teknikker i sandsynlighedsproblemer
Kendskab til tilfældige variabler og deres egenskaber
Forståelse af fælles sandsynlighedsfordelinger
Kvantitativ evne til at løse sandsynlighedsrelaterede problemer
Evne til at resonnere numerisk i sandsynlighedsscenarier

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? A: 17 July 2008 B: 23 Sep 2007 C: 25 July 2009 D: 19 Aug 2008 E: 26 July 2008 F: 28 Nov 2007 G: 11 June 2008 H: 15 Aug 2007

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Sandsynlighedstest 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

Avanceret forståelse af tilfældige variabler
Ekspertise i fælles sandsynlighedsfordelinger

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?

kombinatorik </H4> <P > Kombinatorik er evnen til at tælle og arrangere genstande eller begivenheder. Det omfatter koncepter som permutationer, kombinationer og tællingsprincipperne. Måling af denne færdighed i testen hjælper med at evaluere kandidatens evne til at løse problemer med at arrangere, vælge og tælle objekter, hvilket er vigtigt i forskellige matematiske og statistiske anvendelser. </p> <h4> tilfældige variabler
De Færdighed af tilfældige variabler involverer at forstå begrebet tilfældige variabler og deres sandsynlighedsfordeling. Tilfældige variabler er variabler, hvis værdier afhænger af resultatet af en tilfældig begivenhed. Måling af denne færdighed i testen kan vurdere kandidatens evne til at analysere og fortolke tilfældige fænomener samt anvende sandsynlighedsfordelinger til modellere i virkeligheden i den virkelige verden. til sandsynlighedsfordelingen af to eller flere tilfældige variabler. Denne færdighed involverer at forstå den fælles sandsynlighedsfordeling, betinget sandsynlighed og relaterede koncepter. At inkludere denne færdighed i testen hjælper med at evaluere kandidatens greb om modellering og analyse af forholdet mellem flere tilfældige variabler, hvilket er vigtigt inden for forskellige områder, såsom maskinlæring, finansiering og driftsforskning.

Probability Hiring Test Ofte stillede spørgsmål

Kan jeg kombinere flere færdigheder i en brugerdefineret vurdering?

Ja absolut. Brugerdefinerede vurderinger er oprettet baseret på din jobbeskrivelse og vil omfatte spørgsmål om alle must-have-færdigheder, du angiver.

Har du nogen anti-cheating eller proctoring-funktioner på plads?

Vi har følgende anti-cheating-funktioner på plads:

Ikke-gåbare spørgsmål
IP Proctoring
Webproctoring
Webcam Proctoring
Detektion af plagiering
Sikker browser

Læs mere om Proctoring Features.

Hvordan fortolker jeg testresultater?

Den primære ting at huske på er, at en vurdering er et elimineringsværktøj, ikke et udvælgelsesværktøj. En færdighedsvurdering er optimeret for at hjælpe dig med at eliminere kandidater, der ikke er teknisk kvalificerede til rollen, den er ikke optimeret til at hjælpe dig med at finde den bedste kandidat til rollen. Så den ideelle måde at bruge en vurdering på er at beslutte en tærskelværdi (typisk 55%, vi hjælper dig med benchmark) og inviterer alle kandidater, der scorer over tærsklen for de næste interviewrunder.

Hvilken oplevelsesniveau kan jeg bruge denne test til?

Hver Adaface -vurdering tilpasses til din jobbeskrivelse/ ideel kandidatperson (vores emneeksperter vælger de rigtige spørgsmål til din vurdering fra vores bibliotek på 10000+ spørgsmål). Denne vurdering kan tilpasses til ethvert erfaringsniveau.

Får hver kandidat de samme spørgsmål?

Ja, det gør det meget lettere for dig at sammenligne kandidater. Valgmuligheder for MCQ -spørgsmål og rækkefølgen af spørgsmål randomiseres. Vi har anti-cheating/proctoring funktioner på plads. I vores virksomhedsplan har vi også muligheden for at oprette flere versioner af den samme vurdering med spørgsmål om lignende vanskelighedsniveauer.
