Rewards Activities Order
Database Connection
Solve
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

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 }

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.

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 Technical Aptitude & Python 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.

    Loops in Python enable repetitive execution of code blocks. This includes the for and while loops, which allow the program to iterate over a sequence of elements or continue execution until a specific condition is met. Testing this skill helps determine a candidate's proficiency in implementing efficient and accurate looping logic, which is essential for tasks such as processing large amounts of data or performing iterative calculations.

  • Functions

    Functions in Python are reusable blocks of code that perform specific tasks. They allow for modular programming and facilitate code organization and reusability. Evaluating a candidate's understanding of functions helps assess their ability to write clean and maintainable code, as well as their knowledge of concepts such as function parameters, return values, and scope.

  • Lists

    Lists in Python are ordered collections of elements. They can store different data types and support operations such as element manipulation, indexing, and slicing. Assessing this skill ensures a candidate can work with lists effectively, enabling them to manage and manipulate data in a structured and organized manner.

  • Dictionaries

    Dictionaries in Python are key-value pairs that allow efficient retrieval and storage of data. They provide a way to associate data with unique keys and are useful for tasks such as mapping and indexing. Measuring this skill helps evaluate a candidate's ability to work with dictionaries and utilize their advantages in solving real-world programming problems.

  • File Handling

    File Handling in Python involves reading from and writing to files. It includes operations such as opening, reading, writing, and closing files, as well as handling exceptions that may occur during file operations. Testing this skill gauges a candidate's ability to work with file input/output operations, ensuring they can effectively interact with external data sources.

  • Object-Oriented Programming

    Object-Oriented Programming (OOP) in Python allows the creation and interaction of objects, which encapsulate data and behavior. This includes concepts such as classes, objects, inheritance, and polymorphism. Assessing this skill provides insights into a candidate's understanding of OOP principles and their ability to design and implement modular and maintainable code.

  • Exception Handling

    Exception Handling in Python involves managing and responding to runtime errors and exceptional situations gracefully. This includes using try, except, and finally blocks to handle exceptions, as well as raising and customizing exception classes. Evaluating a candidate's knowledge of exception handling ensures they can write resilient code that gracefully handles errors and prevents program crashes.
