9 reasons why

Adaface Java & Android Test is the most accurate way to shortlist Java -utviklers

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:

I stand til å skrive Java -kode ved hjelp av grunnleggende syntaks og datatyper
Dyktig i objektorienterte programmeringskonsepter i Java
Kunnskapsrik i Java Collections Framework and Data Structures
Kjent med kjernemålet for Android -utvikling

I stand til effektivt håndtering av unntak og feil i Java
Erfarne med å bruke Java -kodingsprinsipper og beste praksis

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.

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 Java & Android Test 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 (objekt- Orientert programmering) innebærer å forstå prinsippene for innkapsling, arv, polymorfisme og abstraksjon i Java. Denne ferdigheten gjør at utviklere kan skrive modulær, vedlikeholdbar og gjenbrukbar kode. Det er viktig å vurdere denne ferdigheten i testen for å evaluere en kandidats evne til å implementere effektive og skalerbare Java -løsninger.
Java -samlinger
Java -samling er et rammeverk som gir implementeringer av ofte brukt Datastrukturer som lister, sett og kart. Det er viktig at utviklere er dyktige i denne ferdigheten å manipulere og lagre data effektivt. Evaluering av denne ferdigheten i testen lar rekrutterere måle en kandidats ferdighet i å bruke disse datastrukturene for å løse problemer i den virkelige verden.
Android Core Framework
Android Core Framework er en samling av Viktige klasser og biblioteker som letter utviklingen av Android -applikasjoner. Det inkluderer komponenter som aktivitet, service, contentprovider og intensjon. Å måle denne ferdigheten i testen hjelper rekrutterere med å vurdere en kandidats forståelse av kjernebyggesteinene til Android -applikasjoner.
Android -komponenter
Android -komponenter er byggesteinene til en Android -applikasjon, for eksempel som aktiviteter, fragmenter og synspunkter. Denne ferdigheten er viktig å vurdere i testen, da den demonstrerer en kandidats evne til å designe og strukturere brukergrensesnittet og funksjonaliteten til en Android -app.
Android -brukerinteraksjonshåndtering
Android brukerinteraksjon Håndtering innebærer å fange og svare på brukerhandlinger i et Android -applikasjon, for eksempel knappeklikk, gester og berøringshendelser. Det er avgjørende å vurdere denne ferdigheten i testen for å sikre at kandidater kan skape intuitive og responsive brukeropplevelser i Android -appene sine.
Java -koding
Java -koding er muligheten til å skrive ren, Effektiv og lesbar kode ved hjelp av Java -programmeringsspråket. Denne ferdigheten omfatter å skrive algoritmer, implementere datastrukturer og anvende beste praksis i Java -utvikling.

Java & Android Hiring Test Vanlige spørsmål

Kan jeg kombinere flere ferdigheter til en tilpasset vurdering?

Ja absolutt. Tilpassede vurderinger er satt opp basert på stillingsbeskrivelsen din, og vil inneholde spørsmål om alle må-ha ferdigheter du spesifiserer.

Har du noen anti-juksende eller proktoreringsfunksjoner på plass?

Vi har følgende anti-juksede funksjoner på plass:

Ikke-googlable spørsmål
IP Proctoring
Nettproctoring
Webcam Proctoring
Deteksjon av plagiering
Sikker nettleser

Les mer om Proctoring -funksjonene.

Hvordan tolker jeg testresultater?

Den viktigste tingen å huske på er at en vurdering er et eliminasjonsverktøy, ikke et seleksjonsverktøy. En ferdighetsvurdering er optimalisert for å hjelpe deg med å eliminere kandidater som ikke er teknisk kvalifisert for rollen, det er ikke optimalisert for å hjelpe deg med å finne den beste kandidaten for rollen. Så den ideelle måten å bruke en vurdering på er å bestemme en terskelpoeng (vanligvis 55%, vi hjelper deg med å benchmark) og invitere alle kandidater som scorer over terskelen for de neste rundene med intervjuet.

Hvilken opplevelsesnivå kan jeg bruke denne testen til?

Hver ADAFACE -vurdering er tilpasset din stillingsbeskrivelse/ ideell kandidatperson (våre fageksperter vil velge de riktige spørsmålene for din vurdering fra vårt bibliotek med 10000+ spørsmål). Denne vurderingen kan tilpasses for ethvert opplevelsesnivå.

Får hver kandidat de samme spørsmålene?

Ja, det gjør det mye lettere for deg å sammenligne kandidater. Alternativer for MCQ -spørsmål og rekkefølgen på spørsmål er randomisert. Vi har anti-juksing/proctoring funksjoner på plass. I vår bedriftsplan har vi også muligheten til å lage flere versjoner av den samme vurderingen med spørsmål med lignende vanskelighetsnivåer.
