Adaface Python & Django Test is the most accurate way to shortlist Python开发人员s



Reason #1

Tests for on-the-job skills

The Python & Django Online Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

  • 能够使用适当的语法和约定编写Python代码
  • 在Python中具有常见数据结构的经验
  • 熟练在桌子上执行CRUD操作
  • 能够有效处理Python中的异常和错误
  • 熟悉Django框架的基础知识
  • 了解Django模型和观点
  • 理解Django模板
  • 精通Python编程
Reason #2

No trick questions

no trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface

Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

这些只是我们库中有10,000多个问题的一个小样本。关于此的实际问题 Python&Django测试 将是不可行的.

Session
File Handling
Dictionary
Try practice test
 image
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?

Recursive Function
Recursion
Dictionary
Lists
Try practice test
Consider the following Python code:
 image
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?
 image
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.

URL Dispatcher
Routes
Try practice test
Review the following sample Django URL.conf:
 image
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:
 image
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:
 image
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.

We want a QuerySet with all Person objects where retired == True and age != 45. Which of the following do you think we should use?
 image

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 Python&Django测试 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 Python&Django测试 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.
