Consider the following SQL table: How many tuples does the following query return?
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# & SQL -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 C# & SQL Online Test?

C# Syntax Basics
C# Syntax Basics refererer til grunnleggende regler og struktur som brukes til å skrive C# -kode. Dette inkluderer forståelse av datatyper, variabler, operatører, kontrollstrukturer og grunnleggende inngangs-/utgangsoperasjoner. Å vurdere denne ferdigheten sikrer at kandidater har en solid forståelse av de grunnleggende byggesteinene for C# -programmering.
C# oops
C# oops (objektorientert programmering) innebærer å designe og lage klasser, objekter , og deres interaksjoner for å løse problemer i den virkelige verden. Denne ferdigheten måler en kandidats evne til å bruke objektorienterte prinsipper som innkapsling, arv og polymorfisme for å utvikle fleksibel og modulær kode.
C# Datastrukturer
C# Datastrukturer er containere for organisere og lagre data effektivt. Dette inkluderer matriser, lister, køer, stabler og ordbøker. Evaluating this skill helps assess a candidate's understanding of the different types of data structures and their application in solving complex programming challenges.
SQL CRUD Operations
SQL CRUD (Create, Read, Update, Slette) operasjoner involverer manipulering av data lagret i en database. Denne ferdigheten tester en kandidats ferdighet i å skrive SQL -uttalelser for å utføre operasjoner som å sette inn poster, hente data, oppdatere eksisterende poster og slette poster fra databasetabeller.
SQL blir med og indekser
SQL -sammenføyning og indekser er viktige konsepter i databasestyring som letter effektiv og optimalisert datainnhenting. Denne ferdigheten måler en kandidats evne til å skrive SQL -spørsmål som innebærer å slå sammen tabeller basert på vanlige kolonner og bruke indekser for å forbedre spørringsytelsen.
C# programmering
C# Programmering vurderer en kandidats generelle kunnskap og Kompetanse i C# programmeringsspråket. Dette inkluderer en kombinasjon av syntaks, objektorienterte konsepter, datastrukturer og problemløsningsevner. Evaluering av denne ferdigheten gir rekrutterere en omfattende forståelse av en kandidats evne til å utvikle applikasjoner ved å bruke C#.

C# & SQL 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.
