Medium Let's Hack CSS Property	Try practice test
Consider the following HTML and CSS: Which additional CSS rule(s) will render the following image? Choose ALL that apply. A: div{ flex-direction : column; align-items : center; } B: div{ flex-direction : row; align-items: center; } C: div{ flex-direction: column; justify-content: center; } D: div{ flex-direction: row; justify-content: center; }
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.
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 Test JavaScript, HTML/CSS e NODEJS 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.

Come interpreto i punteggi dei test?

La cosa principale da tenere a mente è che una valutazione è uno strumento di eliminazione, non uno strumento di selezione. Una valutazione delle competenze è ottimizzata per aiutarti a eliminare i candidati che non sono tecnicamente qualificati per il ruolo, non è ottimizzato per aiutarti a trovare il miglior candidato per il ruolo. Quindi il modo ideale per utilizzare una valutazione è decidere un punteggio di soglia (in genere il 55%, ti aiutiamo a benchmark) e invitiamo tutti i candidati che segnano al di sopra della soglia per i prossimi round di intervista.

Per quale livello di esperienza posso usare questo test?

Ogni valutazione di Adaface è personalizzata per la descrizione del tuo lavoro/ personaggio del candidato ideale (i nostri esperti in materia sceglieranno le domande giuste per la tua valutazione dalla nostra biblioteca di oltre 10000 domande). Questa valutazione può essere personalizzata per qualsiasi livello di esperienza.

Ogni candidato riceve le stesse domande?

Sì, ti rende molto più facile confrontare i candidati. Le opzioni per le domande MCQ e l'ordine delle domande sono randomizzate. Abbiamo anti-cheatri/procuratore in atto. Nel nostro piano aziendale, abbiamo anche la possibilità di creare più versioni della stessa valutazione con questioni di difficoltà simili.
