Rewards Activities Order
Database Connection
Try practice test
A new popular app tracks the activities performed by its users and grants them rewards based on each individual's total activities performed in a year. This data is maintained in a database table (activitesinfo), with the following columns: userid, totalactivities, reward. This year, due to fundraising activity, the company has decided to further reward its users by enhancing the reward as per the following formula: If reward < = 4000, increase it by 2%, If 4000 < reward <= 8000, increase it by 4%, If reward > 8000, increase it by 6%.
The tech team has written three different scripts to calculate increment for each slab, each script is to run as a separate transaction. Here are the three scripts:
Script 1:
For users with reward <= 4000, set reward = reward * 1.02

Script 2:
For users with reward > 4000 and reward <= 8000, set reward = reward * 1.04

Script 3:
For users with reward > 8000, set reward = reward * 1.06
Each script is to be executed separately. Which of the following options will update the rewards as expected:
A: Execute Script 1 followed by Script 2 followed by Script 3
B: Execute Script 2 followed by Script 3; Script 1 running concurrently throughout
C: Execute Script 3 followed by Script 2; Script 1 running concurrently throughout
D: Execute Script 3 followed by Script 2 followed by Script 1
E: Execute Script 2 followed by Script 3 followed by Script 1

Implementing a Browser's Back Button
Stack
Data Handling
Try practice test
You are tasked with implementing the "Back" button functionality in a web browser. This feature allows users to return to previously visited web pages in the order they were viewed. The browser maintains a history of URLs in a data structure. Considering the nature of web browsing, where users can go back multiple steps and then navigate to a new page (at which point the future history should be cleared), which data structure and algorithm would best implement this functionality?
A: Use a heap, add the current URL when navigating to a new page, and remove the top element when the back button is used.
B: Use a queue, enqueue the current URL when navigating to a new page, and dequeue when the back button is used.
C: Use a single stack, push the current URL when navigating to a new page, and pop when the back button is used.
D: Use an array, add the current URL to the end when navigating to a new page, and remove the last URL when the back button is used.
E: Use a linked list, add the current URL to the head when navigating to a new page, and move backwards when the back button is used.
F: Use two stacks, push the current URL to the first stack when navigating to a new page, and use the second stack to store the pages when the back button is used.

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

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 Softwareudviklertest 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.

Science behind Adaface tests
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Softwareudviklertest 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.

What topics are covered in the Software Engineering Online Test?

  • objektorienteret programmering

    Objektorienteret programmering (OOP) er et programmeringsparadigme, der organiserer softwaredesign omkring begrebet objekter, der kan indeholde data og kode. Det fremmer modulær og genanvendelig kode og giver mulighed for lettere vedligeholdelse og ændring af softwaresystemer. Denne færdighed skal måles i testen for at vurdere en kandidats evne til at designe og implementere effektive og skalerbare softwareløsninger ved hjælp af OOP -principper.

  • databasedesign

    Databasedesign involverer design af struktur og organisation af et databasesystem. Det inkluderer definition af tabeller, forhold og begrænsninger for effektivt at gemme og hente data. Denne færdighed er afgørende, da den sikrer dataintegritet, ydeevne og sikkerhed i softwareapplikationer, der er afhængige af databaser til lagring og styring af information.

  • algoritmer og datastrukturer

    algoritmer og datastrukturer er Grundlæggende koncepter inden for datalogi, der beskæftiger sig med design og analyse af effektive algoritmer og dataorganisation. Færdigheder i denne færdighed giver softwareingeniører mulighed for at oprette hurtige og pålidelige softwaresystemer ved at vælge passende algoritmer og datastrukturer, der effektivt løser komplekse problemer.

  • test og kvalitetssikring </H4> <p> Test og kvalitetssikring ( QA) er processen med at evaluere software for at sikre, at den opfylder de ønskede kvalitetsstandarder. Det involverer oprettelse og udførelse af testtilfælde, identifikation og fastgørelse af fejl og validering af softwarefunktionalitet. Denne færdighed er vigtig at måle, da den bestemmer pålideligheden, stabiliteten og brugertilfredsheden af ​​softwareapplikationer. </p> <h4> webudvikling

    webudvikling involverer oprettelse og vedligeholdelse af websteder og webapplikationer. Det inkluderer front-end udvikling, back-end-udvikling og integration af forskellige teknologier til at levere en problemfri og interaktiv brugeroplevelse. Denne færdighed er nødvendig for at vurdere, da webudvikling er et grundlæggende aspekt af moderne softwareteknik.

  • softwaresikkerhed

    Softwaresikkerhed omfatter foranstaltninger, der er truffet for at beskytte softwaresystemer mod uautoriseret adgang, dataovertrædelser og andre sikkerhedstrusler. Det involverer implementering af sikker kodningspraksis, kryptering og godkendelsesmekanismer. Denne færdighed er vigtig, da den sikrer sikkerheden og fortroligheden af ​​følsomme oplysninger i softwareapplikationer.

  • kodeoptimering

    Kodeoptimering er processen med at forbedre effektiviteten og ydelsen af ​​softwarekoden. Det involverer analyse og ændring af kode for at reducere dens udførelsestid, hukommelsesforbrug og ressourceforbrug. Denne færdighed er vigtig at måle, da den demonstrerer en kandidats evne til at skrive meget optimeret og skalerbar kode, hvilket resulterer i hurtigere og mere effektive softwaresystemer.

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.

Jeg er kandidat. Kan jeg prøve en øvelsestest?

Nej. Desværre understøtter vi ikke praksisforsøg i øjeblikket. Du kan dog bruge vores eksempler på spørgsmål til praksis.

Hvad er omkostningerne ved at bruge denne test?

Du kan tjekke vores prisplaner.

Kan jeg få en gratis prøve?

Ja, du kan tilmelde dig gratis og forhåndsvise denne test.

Jeg flyttede lige til en betalt plan. Hvordan kan jeg anmode om en brugerdefineret vurdering?
