Top 10 Python Interview Questions Asked by Pune IT Companies (With Answers) (Updated May 2026)

Trust me — I have seen hundreds of students walk into Python interviews at Pune IT companies completely underprepared, not because they don't know Python, but because they haven't practised the specific questions these companies actually ask. NASSCOM-Deloitte projects a need for 1.25 million AI and software professionals in India by 2027, and right now Infosys, TCS, KPIT, and Wipro's Pune offices are all actively hiring Python developers. The difference between getting the call letter and getting rejected in round one is usually these ten questions.

Why Python Interview Questions Are Different at Pune IT Companies

Pune has a specific flavour of IT hiring that differs from Bengaluru or Hyderabad. Most Pune IT companies — particularly the mid-size ones in Hinjewadi, Kharadi, and Magarpatta — prioritize practical problem-solving over theoretical knowledge. They want to know whether you have actually written Python code on a project, not just completed a certification. The interview process typically has three rounds: a written test with MCQs on core Python, a coding round on HackerRank or similar, and a technical HR round. Here is what actually appears in each of those rounds based on what our students report after interviews.

Q1 to Q3: Core Python Questions That Filter 80 Percent of Candidates

The three questions that eliminate most candidates in round one are: (1) What is the difference between a list and a tuple in Python? Answer — lists are mutable, tuples are immutable; tuples are faster for read-only data. (2) Explain Python's GIL — the Global Interpreter Lock prevents multiple native threads from executing Python bytecodes simultaneously; use multiprocessing for CPU-bound tasks. (3) What are Python decorators? A decorator is a function that takes another function as input and extends its behaviour without modifying it — commonly used for logging, authentication, and caching. Knowing these three cold, with examples, gets you past most first-round filters at Infosys and TCS.

Q4 to Q6: Object-Oriented and Functional Python Questions

Object-oriented questions hit in round two. Q4: What is the difference between __str__ and __repr__? __str__ is for readable output aimed at end users; __repr__ is for unambiguous representation aimed at developers and debugging. Q5: What are Python's four pillars of OOP? Encapsulation, inheritance, polymorphism, and abstraction — be ready to code a real example for each. Q6: What is a lambda function and when would you use one? A lambda is an anonymous, single-expression function — use it for short operations passed to functions like map(), filter(), or sorted(). KPIT Pune specifically asks you to write a lambda to sort a list of dictionaries by a specific key.

Q7 to Q9: Django, Flask, and Framework Questions Asked in Pune

Even if you are not applying for a web development role, Pune IT companies increasingly ask about web frameworks because they want versatile engineers. Q7: What is the difference between Django and Flask? Django is batteries-included — ORM, admin panel, authentication out of the box; Flask is a lightweight microframework for developers who want full control. Q8: What is Django's ORM and how does it work? The ORM (Object-Relational Mapper) lets you interact with your database using Python classes instead of raw SQL. Q9: How do you handle database migrations in Django? You use makemigrations to generate migration files and migrate to apply them — always version-control your migration files. Wipro Pune specifically tests this in their Python technical rounds.

Q10: The Practical Coding Challenge Most Freshers Fail

The practical coding challenge is where most freshers lose marks. A typical Q10 from Pune IT interviews: "Given a list of integers, write a Python function that returns all pairs of numbers that add up to a target sum, without using nested loops." The expected answer uses a set: iterate through the list once, check if (target - current_number) is in the set, add current_number to the set. Time complexity O(n). What trips freshers is not the logic — it's the ability to write clean, readable code with proper variable names, docstrings, and edge case handling (empty list, duplicates, negative numbers). Practice this pattern at least 20 times before your interview.

How to Prepare for Python Interviews at Infosys, TCS, and KPIT Pune

The most effective preparation strategy is to practise mock interviews with someone who has sat on both sides of the table. At ABC Trainings' Python programming course in Pune, we run mock interview sessions using real question banks from Infosys, TCS, KPIT, and Wipro. Students who complete the mock interview module report significantly higher confidence in actual interviews. Pair that with at least one project on GitHub — a Django REST API, a data analysis notebook, or a Flask app with authentication — and you have a profile that stands out in a pile of resumes.

FAQs

What is the most commonly asked Python interview question in Pune IT companies?

The most frequently reported question across Pune IT companies is the difference between a list and a tuple. It sounds basic, but interviewers use follow-up questions (about performance, hashability, and when to use each) to gauge how deeply you really understand Python. Always prepare beyond the surface-level answer.

Do Pune IT companies ask data structures and algorithms in Python interviews?

Yes — especially for mid-level Python roles at KPIT and Bosch India. Freshers at TCS and Infosys are typically tested on basic DSA: sorting, searching, and simple string manipulation in Python. More senior roles require graph traversal, dynamic programming, and time complexity analysis. For fresher preparation, focus on list operations, dictionaries, and the two-pointer or set-based patterns.

Is Python enough to get hired at TCS or Infosys Pune as a fresher?

Python alone gets you interviews, but a project portfolio closes the deal. Freshers with a Django REST API project or a data analysis project on GitHub consistently get more callbacks than those with just a Python certificate. Add one real project and you move from "maybe" to "shortlisted" at most Pune IT companies.

Where can I practise Python interview questions with real trainers in Pune?

ABC Trainings runs Python programming courses with mock interview modules at Wagholi and Hadapsar in Pune, Cidco and Osmanpura in Chh. Sambhajinagar, and Sangli. Our question bank includes real interview questions reported by students placed at Infosys, TCS, and KPIT. Call 7039169629 or WhatsApp 7774002496 for batch schedules.
