9 reasons why

Adaface C Online test is the most accurate way to shortlist Core C Developers

Reason #1

Tests for on-the-job skills

C Online -test er designet og validert av bransjeeksperter for å hjelpe teknologiske rekrutterere og ansettelsesledere med å vurdere C -programmeringsferdighetene til kandidaten. Topp teknologiselskaper bruker vår JavaScript -programmeringstest for å redusere kandidat -screeningtiden med 85%.

Testen er designet for å filtrere ut kandidater for roller som

Junior C -utvikler
C -utvikler
mellomliggende C -utvikler
Senior C -utvikler
Backend Developer

Testen sikrer at kandidatene har følgende egenskaper:

Evne til å skrive gjenbrukbar C -kode
Kompetanse i datastrukturer
Dyp kunnskap om pekere, strukturer og fagforeninger
Utmerket kunnskap om frontend -programmeringsspråk og relaterte rammer
Evne til å identifisere områder for modifisering i eksisterende programmer og deretter utvikle disse modifikasjonene
Hands-on feilsøkings- og utviklingsferdigheter
Opplev integrering av flere datakilder og databaser
Evne til å utføre endringer og bryte rettelser med VBA -kode og C -programmer
Erfaring med skriveenhet og funksjonelle tester

C Online -test er hovedsakelig designet for å vurdere kandidater som har høy evne innen C -koding, og kunnskap om forskjellige funksjoner. I denne testen må programmereren skrive kode ved hjelp av C -kodingsspråk.

For hver kandidat vil du motta en detaljert rapport for å hjelpe deg med å ta objektive, datadrevne beslutninger og identifisere de beste kandidatene. Testen fokuserer på spørsmål som tester for ferdigheter på jobb C i motsetning til teoretisk kunnskap.

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.

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.

Why we started Adaface ->

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.

Dette er bare en liten prøve fra biblioteket vårt med 10.000+ spørsmål. De faktiske spørsmålene om dette C Online Test vil være ikke-googlable.

🧐 Question
Medium Memory Allocation	Solve
Check the following three C functions: Which among these will likely cause issues with pointers?
Medium Pointers and Structs	Solve
What is the output of the following C code?
Medium Strings Strings	Solve
What is the output of the following C code?
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 C Online 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the C Online Test 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.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

Om C -utviklerrollen

C er et generelt formål, prosessuell dataprogrammeringsspråk som støtter strukturert programmering, leksikalsk variabelt omfang og rekursjon, mens et statisk type system forhindrer utilsiktet operasjoner.

C-utviklere er generelt ansvarlige for å utvikle kode som integreres i operativsystemer, operativsystemmoduler, innebygde systemer eller biblioteker på lavt nivå for andre språk på høyt nivå som Node.js, Python og Go.

Typisk ansvar for en C -utvikler ville være:

Design, bygge og vedlikeholde effektiv, gjenbrukbar og pålitelig C -kode
Identifiser prosessflaskehalser og feil
Utvikle kjernemoduler, biblioteker og innebygde systemer for andre språk på høyt nivå
Oppretthold automatiseringen og kvaliteten på koden

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.

Jeg er en kandidat. Kan jeg prøve en praksisprøve?

Nei. Dessverre støtter vi ikke praksisprøver for øyeblikket. Du kan imidlertid bruke eksemplet spørsmål for praksis.

Hva koster ved å bruke denne testen?

Du kan sjekke ut prisplanene våre.

Kan jeg få en gratis prøveperiode?

Ja, du kan registrere deg gratis og forhåndsvise denne testen.

Jeg flyttet nettopp til en betalt plan. Hvordan kan jeg be om en tilpasset vurdering?
