🧐 Question
Medium ZeroDivisionError and IndexError Exceptions	Try practice test
What will the following Python code output?
Medium Session File Handling Dictionary	Try practice test
The function high_sess should compute the highest number of events per session of each user in the database by reading a comma-separated value input file of session data. The result should be returned from the function as a dictionary. The first column of each line in the input file is expected to contain the user’s name represented as a string. The second column is expected to contain an integer representing the events in a session. Here is an example input file: Tony,10 Stark,12 Black,25 Your program should ignore a non-conforming line like this one. Stark,3 Widow,6 Widow,14 The resulting return value for this file should be the following dictionary: { 'Stark':12, 'Black':25, 'Tony':10, 'Widow':14 } What should replace the CODE TO FILL line to complete the function?
Medium Max Code Arrays	Try practice test
Below are code lines to create a Python function. Ignoring indentation, what lines should be used and in what order for the following function to be complete:
Medium Recursive Function Recursion Dictionary Lists	Try practice test
Consider the following Python code: In the above code, recursive_search is a function that takes a dictionary (data) and a target key (target) as arguments. It searches for the target key within the dictionary, which could potentially have nested dictionaries and lists as values, and returns the value associated with the target key. If the target key is not found, it returns None. nested_dict is a dictionary that contains multiple levels of nested dictionaries and lists. The recursive_search function is then called with nested_dict as the data and 'target_key' as the target. What will the output be after executing the above code?
Medium Stacking problem Stack Linkedlist	Try practice test
What does the below function ‘fun’ does? A: Sum of digits of the number passed to fun. B: Number of digits of the number passed to fun. C: 0 if the number passed to fun is divisible by 10. 1 otherwise. D: Sum of all digits number passed to fun except for the last digit.
Easy URL Dispatcher Routes	Try practice test
Review the following sample Django URL.conf: Pick the correct statements if settings.APPEND_SLASH=False: A: A request to /books/2015/04/ would match the third entry in the list. Django would call the function views.month_books(request, year=2015, month=4). B: A request to /books/2015/04/ would match the second entry in the list. Django would call the function views.year_books(request, year=2015). C: A request to /books/2023/ will match the first entry in the list. Django would call the the function views.custom_newyear_2023(request). D: A request to /books/2023/ would match the second entry in the list. Django would call the function views.year_books(request, year=2023). E: /books/2022 would not match any of these patterns, because each pattern requires that the URL end with a slash. F: A request to /books/2022 would match the second entry in the list. Django would call the function views.year_books(request, year=2022).
Medium External Bank Transfer Database Transactions	Try practice test
Review the following Django code for a banking application: The code needs to debit an account with the provided amount and deposit the amount in an external entity. Here’s how the code is broken: 1) First, the amount is debited from the account by creating a new row in BalanceLine table. 2) Next, a new row is created in the DB in ExternalTransfer table and a new id (used as unique reference) is created for the transfer. 3) An external 3rd party API call is made using the new id created in step 2. The function transfer_to_other_bank is called as shown below: Pick the correct statements: A: If post_transfer_emails() raises an exception, the database transactions that happened in transfer_to_other_bank are not rolled back since they are listed in a separate atomic transaction. B: If post_transfer_emails() raises an exception, the database transactions (new rows in ExternalTransfer and BalanceLine tables) are rolled back. The banking_api call is called again with a null reference. C: If post_transfer_emails() raises an exception, the database transactions are rolled back but the banking_api is not called again. D: If post_transfer_emails() raises an exception, the banking_api is called again with rollback=True. If the response is success, then the database transactions are rolled back. If the response is failure, the database transactions are committed.

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 Python, Django & SQL 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.

En savoir plus sur les fonctionnalités de Proctoring.

Comment interpréter les résultats des tests?

La principale chose à garder à l'esprit est qu'une évaluation est un outil d'élimination, pas un outil de sélection. Une évaluation des compétences est optimisée pour vous aider à éliminer les candidats qui ne sont pas techniquement qualifiés pour le rôle, il n'est pas optimisé pour vous aider à trouver le meilleur candidat pour le rôle. Ainsi, la façon idéale d'utiliser une évaluation consiste à décider d'un score de seuil (généralement 55%, nous vous aidons à bencher) et à inviter tous les candidats qui marquent au-dessus du seuil pour les prochains cycles d'entrevue.

Pour quel niveau d'expérience puis-je utiliser ce test?

Chaque évaluation ADAFACE est personnalisée à votre description de poste / Persona de candidats idéaux (nos experts en la matière choisiront les bonnes questions pour votre évaluation de notre bibliothèque de 10000+ questions). Cette évaluation peut être personnalisée pour tout niveau d'expérience.

Chaque candidat reçoit-il les mêmes questions?

Oui, cela vous permet de comparer les candidats. Les options pour les questions du MCQ et l'ordre des questions sont randomisées. Nous avons Anti-Cheating / Proctoring en place. Dans notre plan d'entreprise, nous avons également la possibilité de créer plusieurs versions de la même évaluation avec des questions de niveaux de difficulté similaires.

Je suis candidat. Puis-je essayer un test de pratique?

Non. Malheureusement, nous ne soutenons pas les tests de pratique pour le moment. Cependant, vous pouvez utiliser nos exemples de questions pour la pratique.
