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:

Evne til at konfigurere og konfigurere en Express.js -applikation
Kendskab til routing i Express.js til håndtering af forskellige slutpunkter
Forståelse af servering af statiske filer i Express.js
Erfaring med at skabe og bruge Middlewares i Express.js
Evne til at bruge skabelonmotorer til dynamisk indhold i Express.js
Færdigheder i fejlfinding Express.js applikationer
Forståelse af Node.js Fundamentals
Stærk viden om JavaScript -kodning
Erfaring med håndtering af undtagelser og fejl
Kapacitet til at optimere ydeevne i Express.js -applikationer

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 I/O cycle and main module Event Loop	Try practice test
Review the following NodeJS code: Pick the correct statements: A: X will be logged after Y always B: Y will be logged after X always C: The order of executing timeout and immediate callbacks is non-deterministic and is bound by the performance of the process D: In this case, the function calls are scheduled in the main module and not in the I/O cycle E: In this case, the function calls are scheduled in the I/O cycle so setImmediate is always executed before any timers scheduled in the I/O phase, independently of how many timers are left
Easy Res methods	Try practice test
If none of the methods (res.download, res.end, res.json, res.jsonp, res.redirect, res.render, res.send, res.sendFile, res.sendStatus) are called from a route handler to terminate request response cycle, what happens to the the client request? A) Will be left hanging indefinitely B) Will get an internal server error - 500 C) Will get a service unavailable error - 503 D) Will be left hanging for a while and then request timeout error - 408
Medium Phases and Timers Event Loop	Try practice test
Review the following NodeJS code: Pick the correct statements: A: Adaface will be logged after Lovelace. B: Lovelace will be logged after Adaface. C: Once the asyncOpThatTakes195ms completes reading the file, it starts executing the callback which takes 10 seconds. Only after this is finished, the event loop will execute the timers that are finished. So the timeout call back will actually be executed after 205 ms even though it is scheduled to be run after 200 ms D: Once the asyncOpThatTakes195ms completes reading the file, it starts executing the callback. While executing the callback, the scheduled timer becomes ready to be executed. So the runtime executes the timer and then completes processing the callback.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Expressjs 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.

About the ExpressJS Online Test

Why you should use Pre-employment ExpressJS Test?

The Expressjs test makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

Routing in Express
Opsætning af Express -applikation
Serverer statiske filer i Express
Oprettelse og brug af Middlewares i Express
Brug af skabelonmotorer
Debugging Express
Node.js Fundamentals
JavaScript -kodning
Autentificering og tilladelse i Express
Databaseintegration i Express

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 ExpressJS Test?

servering af statiske filer i Express
Servering af statiske filer i Express giver applikationen mulighed for at betjene HTML, CSS, JavaScript og andre statiske filer til klienten. Det sikrer, at websiderne gengives korrekt, og de nødvendige aktiver indlæses, hvilket gør det til en vigtig færdighed for webudvikling.
Oprettelse og brug af mellemgældende der har adgang til anmodning og svarobjekter. De kan bruges til at tilføje funktionalitet, udføre validering, håndtere fejl og mere. At være i stand til at oprette og bruge mellemgældende er vigtigt for at opbygge robuste og skalerbare applikationer. </p> <h4> Brug af skabelonmotorer </H4> <p> Skabelonmotorer i Express Tillad den dynamiske generation af HTML -sider ved at kombinere skabeloner med data . De forenkler processen med at gengive HTML på serveren og aktiverer genbrug af kode. Forståelse og brug af skabelonmotorer er afgørende for at udvikle dynamiske webapplikationer. </p> <h4> fejlfinding Express
Debugging Express involverer identificering og fastgørelse af problemer eller fejl i applikationskoden. Det kræver forståelse af fejlmeddelelserne, ved hjælp af debugging -værktøjer og fejlfinding af koden for at sikre jævn drift. Det er nødvendigt at være dygtig til at fejlsøge ekspress-applikationer for at levere software af høj kvalitet.
node.js Fundamentals
node.js Fundamentals omfatter kernekoncepter og funktioner i Node.js, inklusive begivenhed -drevet arkitektur, ikke-blokerende I/O, moduler og filsystemoperationer. Kendskab til node.js Fundamentals er vigtig, da Express.js er bygget oven på Node.js og forståelse af, hvordan det fungerer under hætten, hjælper med at opbygge effektive applikationer.
javaScript -kodning
JavaScript -kodning henviser til muligheden for at skrive ren, effektiv og vedligeholdelig kode ved hjælp af JavaScript -programmeringssprog. Stærke JavaScript-kodningsevner er vigtige for at udvikle applikationer på serversiden ved hjælp af Express.js og effektivt ved hjælp af de forskellige funktioner og funktionaliteter, den tilbyder.

ExpressJS 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.
