Round 2: Technical Interview
Make every effort to be ready for this phase of the hiring process as it is the most difficult. Your technical expertise, biography, and main projects will be the main topics of discussion during the entire interview process.
The face-to-face technical round of the TCS interview consists of questions meant to gauge a candidate’s understanding of object-oriented programming concepts, database management systems, networking, operating systems, and data structures and algorithms. You can also use this round to test your programming language knowledge. It’s highly likely that you’ll be required to write some code by hand.
Round 3: Managerial Round
- Senior members of the panel oversee the management round. This round of interviews is also in-person. This round could have only technical questions, or it could have both technical and managerial questions.
- Most of the questions are tailored to the profile you are interviewing for. For such role, you should be knowledgeable about any new software or technology.
- To find out more about your thinking style, you might also be given questions based on your behaviour. To see how you respond, you can be put under pressure.
- You might need to defend the accomplishments listed on your CV if they are called into question. Your goals, past employment history, reasons for joining TCS, and other related subjects can be the subject of questions.
- In this round, the panel will evaluate your desired career advancement, soft skills, attitude, and fit with the company culture, among other things.
- Generic inquiries concerning your professional background, educational background, area of expertise, wish to move, and other topics may also be made. In any case, maintain your composure no matter how the interview goes.
- The goal of the interview panel is to have you venture beyond your comfort zone. Retain your calm and answer the questions you know the answers to. I

The intention is to remain friendly and self-assured. Keep in mind that interviews can be tiresome and drawn out, so smile!
Top TCS python Interview Questions
Q1. What is a Python script? What advantages does Python offer?
- Python is a general-purpose programming language that has a simple, easy-to-learn syntax that emphasizes readability and therefore reduces the cost of program maintenance.
- Moreover, the language is capable of scripting, is completely open-source, and supports third-party packages encouraging modularity and code reuse.
- Its high-level data structures, combined with dynamic typing and dynamic binding, attract a huge community of developers for Rapid Application Development and deployment.
Q2. What is dynamically typed language?
Q3. What is PEP 8 and explain its significance?
Q4. What does Python scope mean?
- The local objects accessible in the current function are referred to as the local scope.
- The items that have been accessible since the beginning of code execution are referred to as the global scope.
- The global objects of the current module that are accessible within the programme are referred to as a module-level scope.
- The term “outermost scope” describes all of the program’s callable built-in names. The name mentioned is found by searching the items in this scope last.
Q5. What are lists and tuples? What are the key difference between them?
Q6. What is pass in Python?
def myEmptyFunc():
# do nothing
pass
myEmptyFunc() # nothing happend
## Without the pass keyword
# File "<stdin>", line 3
# IndentationError: expected an indented blockQ7. What are modules and packages in Python?
Q8. What are global, protected and private attributes in Python?
Answer:
- Public variables defined within the global scope are referred to as global variables. We utilise the global keyword inside a function to access the variable in the global scope.
- Protected attributes are those that have an underscore (_sara, for example) prefixed to their identification. Although they are still accessible and modifiable from outside the class in which they are declared, a prudent developer should not do so.
- Private attributes are those that have a double underscore (__ansh) prefixed to their identifier. They cannot be directly accessed or modified from the outside, and any effort to do so would raise an AttributeError.
Q9. What is the use of self in Python?
Q10. What are unit tests in Python?
Answer:
- Python’s unit testing framework is called unit test.
- Unit testing is the process of testing individual software components.
- For this reason, it’s essential to thoroughly test every component to identify the one that may be mostly to blame for the software’s failure.
Q11. What is docstring in Python?
Answer:
- A multiline string known as a documentation string, or docstring, is used to describe a particular code segment.
- The function or method’s purpose should be explained in the docstring.
Q12. What is slicing in Python?
Answer:
- As the term implies, “slicing” refers to removing portions.
- Slicing has the syntax [start : stop : step].
- start is the index to begin slicing a list or tuple from.
- The finishing index, or where to sop, is stop.
- The number of steps to jump is called step.
- Start is set to 0, step is set to the number of items, and stop is set to 1.
- Lists, tuples, arrays, and strings can all be chopped.
Q13. What is Scope Resolution in Python?
Answer: Objects in the same scope may have various functions under different names. In these situations, Python’s scope resolution mechanism kicks in immediately. Some instances of this kind of behaviour are:
- There are numerous functions shared by the two Python modules “math” and “cmath,” such as log10(), acos(), and exp(). It is need to prefix them with the appropriate module, such as math.exp() and cmath.exp(), in order to clear up this issue.
Q14. What are the difference between .py and .pyc files?
Answer:
- The program’s source code is contained in.py files. The bytecode of your programme is contained in the.pyc file, however. After the.py file (source code) is compiled, we obtain bytecode. Not every file you execute results in a.pyc file being created. It is made exclusively for the files you import.
- A Python program’s interpreter looks for the built files before running it. The virtual computer runs the file if it exists. It looks for a.py file if it cannot be found. If it is located, it is compiled into a.pyc file and run on a Python virtual machine.
- Compilation time is reduced when you have a.pyc file
Q15. How Python is interpreted?
Answer:
- Python is not compiled or interpreted like a language. Compiling or interpreting is an implementation-specific characteristic. Python is interpreted generally and is a bytecode (collection of interpreter accessible instructions).
- Source code is contained in files ending with.py.
- Python assembles the source code into a virtual machine’s set of instructions. One implementation of that virtual machine is the Python interpreter. “Bytecode” is the name of this intermediate format.
- The.py source code is first compiled to produce bytecode (.pyc). PyPy’s Just in Time (JIT) compiler or the standard CPython can then interpret this bytecode.
Q16. How are arguments passed by value or by reference in python?
Answer:
- Pass by value: The real object is supplied as a copy. The value of the original object remains unchanged if the duplicate of the object is altered.
- Pass by reference: The real object is supplied as a reference. The value of the original object will change if the value of the new object changes.
 Q17. What is iterators in Python?
Answer:
- An iterator is an object.
- It remembers its state i.e., where it is during iteration (see code below to see how)
- __iter__() method initializes an iterator.
- It has a __next__() method which returns the next item in iteration and points to the next element. Upon reaching the end of iterable object __next__() must return StopIteration exception.
- It is also self-iterable.
- Iterators are objects with which we can iterate over iterable objects like lists, strings, etc.
Q18. What are lambda functions?
19. What is PYTHONPATH.
20. What is PIP.
