🧐 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:

Ruting i ekspress
Sette opp Express -applikasjon
Serverer statiske filer i Express
Opprette og bruke mellomvarer i Express
Ved hjelp av malmotorer
Debugging Express
Node.js grunnleggende
JavaScript -koding
Autentisering og autorisasjon i Express
Databaseintegrasjon 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?

Ruting i ekspress
Ruting i ekspress refererer til hvordan applikasjonen håndterer forskjellige HTTP -forespørsler og leder dem til den aktuelle ruten. Det kartlegger i hovedsak den forespurte URL -en til den tilsvarende behandlerfunksjonen eller mellomvaren, noe De nødvendige avhengigheter, konfigurere applikasjonsinnstillingene og opprette den grunnleggende filstrukturen. Denne ferdigheten er viktig fordi den legger grunnlaget for å utvikle og kjøre en uttrykkelig applikasjon.
servering av statiske filer i Express
som serverer statiske filer i Express lar applikasjonen tjene HTML, CSS, JavaScript og andre statiske filer til klienten. Det sikrer at websidene er riktig gjengitt og de nødvendige eiendelene lastes, noe som har tilgang til forespørsels- og svarobjekter. De kan brukes til å legge til funksjonalitet, utføre validering, håndtere feil og mer. Å kunne opprette og bruke mellomvarer er viktig for å bygge robuste og skalerbare applikasjoner.
Bruke malmotorer
Malmotorer i Express Tillat dynamisk generering av HTML -sider ved å kombinere maler med data . De forenkler prosessen med å gjengi HTML på serveren og aktivere gjenbruk av kode. Å forstå og bruke malmotorer er avgjørende for å utvikle dynamiske webapplikasjoner.
Feilsøking Express
Debugging Express innebærer å identifisere og fikse problemer eller feil i applikasjonskoden. Det krever å forstå feilmeldingene, bruke feilsøkingsverktøy og feilsøke koden for å sikre jevn drift. Å være dyktig i å feilsøke Express-applikasjoner er nødvendig for å levere programvare av høy kvalitet.
node.js Fundamentals
node.js Fundamentals omfatter kjernekonseptene og funksjonene til node.js, inkludert hendelse -Drevet arkitektur, ikke-blokkerende I/O, moduler og filsystemoperasjoner. Kunnskap om Node.js Fundamentals er viktig ettersom Express.js er bygget på toppen av Node.js og forstå hvordan det fungerer under panseret hjelper til med å bygge effektive applikasjoner.
JavaScript -koding
JavaScript -koding refererer til muligheten til å skrive ren, effektiv og vedlikeholdbar kode ved hjelp av JavaScript -programmeringsspråket. Sterke JavaScript-kodingsevner er avgjørende for å utvikle server-side-applikasjoner ved bruk av Express.js og effektivt bruke de forskjellige funksjonene og funksjonalitetene det tilbyr.

ExpressJS 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.
