Q34. How does Python handle memory management?
Answer: Python uses automatic memory management with reference counting and a garbage collector. When objects are no longer referenced, Python's garbage collector reclaims memory. This helps prevent memory leaks, as it automatically frees up memory for unused objects. Additionally, Python has a private heap for all its objects, and the memory manager handles all allocations and deallocations.
Q35. Explain polymorphism in object-oriented programming with an example in Java.
Answer: Polymorphism in Java allows objects to be treated as instances of their parent class, and the actual method that gets called is determined at runtime. This allows for flexibility in code and the ability to extend functionality without altering existing code.
class Animal {
void sound() {
System.out.println("Animal makes a sound");
}
}
class Dog extends Animal {
@Override
void sound() {
System.out.println("Dog barks");
}
}
public class Test {
public static void main(String[] args) {
Animal myAnimal = new Animal();
Animal myDog = new Dog(); // Polymorphism
myAnimal.sound(); // Outputs: Animal makes a sound
myDog.sound(); // Outputs: Dog barks
}
}
Output
Animal makes a sound
Dog barks
Q36. How do you handle debugging in Python?
Answer: In Python, I use several methods for debugging:
- Print Statements: I insert print statements to track variable values and program flow.
- Logging Module: For more advanced debugging, I use Python's `logging` module, which provides timestamped logs and different logging levels.
- Python Debugger (pdb): I can use `pdb` to step through code line by line, inspect variables, and set breakpoints.
- IDEs: Integrated Development Environments (IDEs) like PyCharm and VS Code offer built-in debuggers to pause execution and inspect the state of the program interactively.
Q37. How do you prioritize tasks when working in a team?
Answer: I prioritize tasks based on their urgency and importance. First, I identify tasks that are critical for the project’s success or those that depend on other tasks being completed. Then, I break down larger tasks into smaller, manageable ones and ensure that deadlines are realistic. I communicate with the team to ensure alignment on priorities, adjusting when needed to meet goals. Regular check-ins help ensure that tasks are progressing smoothly and to handle any unexpected challenges.
Q38. Can you explain the difference between a stack and a queue? Provide an example in C++.
Answer: A stack is a Last-In-First-Out (LIFO) data structure where the last element added is the first one to be removed. A queue is a First-In-First-Out (FIFO) data structure where the first element added is the first one to be removed.
int main() {
// Stack Example
std::stack s;
s.push(10);
s.push(20);
s.pop(); // Removes 20, as it's the last element added
// Queue Example
std::queue q;
q.push(10);
q.push(20);
q.pop(); // Removes 10, as it's the first element added
}
Q39. How do you communicate technical information to non-technical stakeholders?
Answer: When communicating technical information to non-technical stakeholders, I focus on simplifying complex concepts by using analogies or visual aids like diagrams. I avoid jargon and provide real-world examples to make the technical aspects more relatable. I also make sure to actively listen to their concerns and tailor the information to their specific needs or goals, ensuring they understand the impact of technical decisions on the business.
Q40. What is your approach to problem-solving when faced with a challenging bug in code?
Answer: My approach to problem-solving is methodical:
- Reproduce the Bug: I first try to reproduce the issue to understand the problem more clearly.
- Analyze the Code: I carefully review the code to check for logical errors, edge cases, or improper handling of data.
- Isolate the Issue: I use debugging tools to step through the code and isolate where the problem occurs.
- Test Solutions: Once I identify potential causes, I test different solutions and ensure that the fix does not introduce new issues.
- Document and Reflect: After resolving the bug, I document the solution and any lessons learned to avoid similar issues in the future.
Q41. How do you handle conflicts within a development team?
Answer: In handling conflicts, I first encourage open communication between the involved parties. I listen to both sides without judgment to understand their perspectives. I then guide the team toward a compromise or solution that aligns with the project’s goals. If necessary, I escalate the issue to a team lead or manager to ensure a fair resolution. My focus is on maintaining a collaborative and respectful environment to ensure the team can work effectively together.
Q42. How do you ensure efficient teamwork when working on a large codebase?
Answer: To ensure efficient teamwork on a large codebase, I follow best practices such as:
- Version Control: We use Git for version control, ensuring that all team members can track changes and collaborate without overwriting each other's work.
- Code Reviews: I encourage regular code reviews to maintain code quality and consistency across the project.
- Modular Code: I focus on writing modular, well-documented code to make it easier for others to understand and extend.
- Clear Communication: We hold regular meetings to discuss progress, and blockers, and ensure everyone is on the same page.
- Task Management: We use project management tools like Jira or Trello to track tasks and allocate work efficiently.

- Use exception handling (try-catch) if necessary.
Wipro Accounts Interview Questions
These questions are targeted at candidates applying for roles in the accounts department. Expect questions like:
Q45. Explain the basic accounting principles.
- Accrual Principle: Revenue and expenses are recorded when earned or incurred, not when cash is exchanged.
- Consistency Principle: The same accounting methods must be used consistently from period to period.
- Going Concern Principle: Assumes a business will continue operating indefinitely.
- Prudence (Conservatism) Principle: Avoids overestimating income or assets and underestimating liabilities.
- Economic Entity Assumption: Separates the financial activities of the business from personal transactions.
- Matching Principle: Expenses should be recorded in the same period as the revenue they generate.
- Cost Principle: Assets should be recorded at their original cost, not current market value.
- Full Disclosure Principle: Requires all relevant information to be disclosed in financial statements.
- Time Period Principle: Divides a business’s activities into consistent time periods for reporting.
- Materiality Principle: Small transactions that don't affect financial decisions may be ignored.
Q46. How do you handle financial reconciliations?
- Gather Relevant Documents: Start by collecting all necessary documents such as bank statements, credit card statements, receipts, and invoices. Ensure you have the full set of records for the reconciliation period.
- Match Transactions: Compare the transactions recorded in the company’s books with those in the external sources (e.g., bank statements). Ensure that all entries from both sources match.
- Identify Discrepancies: Look for any differences between the two sets of records. Discrepancies could arise due to timing differences (e.g., checks written but not cleared), missing entries, or errors in recording transactions.
- Adjust Entries: If discrepancies are identified, make adjustments to the financial records, such as correcting errors or updating entries. For example, if a payment was made but not recorded, you would add that payment to the books.
- Investigate Unreconciled Items: For any items that cannot be immediately reconciled, investigate further. This may involve contacting the bank or the relevant parties (e.g., vendors, customers) to clarify the discrepancies.
- Document Adjustments: Keep a record of all adjustments made during the reconciliation process. This documentation will help in auditing and provide a clear trail for future reference.
- Verify with Supporting Documents: Cross-check adjusted transactions with supporting documents, such as receipts, contracts, and invoices, to ensure accuracy.
- Reconcile Periodically: Perform reconciliations on a regular basis (e.g., monthly or quarterly) to catch discrepancies early, ensuring that financial records are always up-to-date.
- Ensure Compliance: Ensure that the reconciliation process follows the company’s internal controls and complies with accounting standards (e.g., GAAP or IFRS).
- Review and Report: After reconciliation, review the final reconciled accounts, and prepare reports for management. Any unresolved discrepancies should be flagged for further investigation.
Wipro Automation Testing Interview Questions
For candidates applying for automation testing roles, common questions may include:
Q47. What is Selenium and how do you use it for automation testing?
- Set Up Selenium WebDriver: To start using Selenium, you'll need to set up the Selenium WebDriver, which is an API that allows you to control browsers programmatically. You can install it using the appropriate programming language bindings (e.g., Java, Python).
- Write Test Scripts: Using Selenium’s WebDriver, you write test scripts that perform actions such as clicking buttons, entering text into forms, verifying page content, navigating through pages, and more.
- Execute Tests: Run the scripts on different browsers or on a remote server to simulate real-user interactions. Selenium can be integrated with tools like TestNG or JUnit for executing the test cases and generating reports.
- Cross-Browser Testing: You can run the same tests on different browsers to ensure cross-browser compatibility.
- Integration with CI/CD: Selenium can be integrated into Continuous Integration/Continuous Deployment (CI/CD) pipelines using tools like Jenkins, allowing for automated testing as part of the build and deployment process.
Q48. Explain the concept of test-driven development.
1. Write a Failing Test: Write a test for a new feature or functionality, ensuring that it initially fails because the code that makes it pass hasn’t been written yet.
- Example: A test that checks if a function correctly calculates the sum of two numbers.
2. Write the Minimum Code to Pass the Test: Write the simplest code that is necessary to pass the test. The goal is not to write the most efficient or complete code but to just make the test pass.
- Example: Write a function that calculates the sum of two numbers and returns the result.
- Example: Refactor the function to handle different data types or edge cases.
