(5 Questions)
- Q1. Explain the difference between lists and tuples.
- Ans.
Lists are mutable, ordered collections of items while tuples are immutable, ordered collections of items.
Lists are mutable, meaning their elements can be changed after creation, while tuples are immutable and cannot be changed.
Lists are defined using square brackets [] while tuples are defined using parentheses ().
Lists are typically used for collections of similar items that may need to be modified, while tuples are u...
- Q2. How does Python handle conditional statements?
- Ans.
Python handles conditional statements using if, elif, and else keywords to control the flow of the program.
Python uses if, elif, and else keywords to create conditional statements.
Indentation is crucial in Python to determine the scope of the conditional statements.
Example: if x > 5: print('x is greater than 5')
Example: if x > 5: print('x is greater than 5') elif x == 5: print('x is equal to 5') else: print('x is less ...
- Q3. Explain the difference between for and while loops in Python
- Ans.
for loop is used for iterating over a sequence while while loop is used for executing a block of code repeatedly as long as a condition is true
For loop is used when the number of iterations is known, while loop is used when the number of iterations is unknown
For loop is more concise and readable for iterating over sequences like lists, while loop is more flexible for complex conditions
Example: for i in range(5): print(...
- Q4. How do you define a function in Python?
- Ans.
A function in Python is defined using the 'def' keyword followed by the function name and parameters.
Use the 'def' keyword followed by the function name and parameters enclosed in parentheses.
Indent the function body to define the code block.
Use the 'return' statement to return a value from the function.
Example: def greet(name): print('Hello, ' + name)
Example: def add_numbers(a, b): return a + b
- Q5. What is the difference between a class and an object?
- Ans.
A class is a blueprint for creating objects, while an object is an instance of a class.
A class defines the properties and behaviors that objects of that class will have.
An object is a specific instance of a class, with its own unique data and behavior.
Classes can be thought of as templates, while objects are the actual instances created from those templates.
Example: Class 'Car' defines properties like 'color' and behav...

Round duration - 120 minutes
Round difficulty - Medium
This was an online coding, mcq and debugging round round held on Amcat platform, there were 3 sections in the test.
1)20 MCQ questions {10 involving mathematics and the other 10 on programming fundamentals}; duration:20 mins;
you cannot navigate back to a questions after moving further, so have to answer carefully
2)debugging section- it involved 7 questions which were to be completed within 20 mins, 5 of them were very easy, each question only took almost a minute to figure out the problem with the code, last 2 questions were relatively moderate and there were errors at 3-4 sections of the entire code. I was able to solve all the questions in 15 mins
3)2 Coding questions- duration:80 mins, one was moderate on string while the other one involved dynamic programming, I was able to successfully execute all the available test cases.

The interview started with introduction, there were two interviewers, they both introduced themselves and then asked me to introduce myself. Then we had a brief description on my projects, and they really appreciated my projects. Then as they were more concerned with DSA part, so we moved towards solving a coding problem. It was a famous rotten oranges problem with some change in language but as I haven't seen it beforehand, I wasn't able to give them an optimal approach and had to ask for some hints, but with a certain amount of help and hints, I was able to solve the problem and successfully coded it in 5 mins. Then the interviewers went for a dry run of the algorithm and tried to run it on each and every corner case, but as my algorithm was kind of bullet proof, it successfully passed all the corner cases.
Then they went for some questions on OOPS concepts involving inheritance and we had a long discussion on virtual function and runtime polymorphism. Then the interview was ended after a Q/A round that lasted for 3-4 minutes.

Example: For input grid = [[2,1,1],[1,1,0],[0,1,1]], the minimum time to...
Interview Preparation Tips
Tip 1 : Try to keep yourself involved in competitive programming on regular basis {ex-Codechef, codeforces etc}
Tip 2 : brush up concepts on DSA and practice at least all questions from interviewbit and around 300 questions from GFG and Leetcode of upto intermediate level, this will help you in building your concepts and you will be quickly able to answer the questions in face to face interviews
Tip 3 : Complete some courses on data structures and algorithms and some programming languages{coding ninjas courses are preferable for valuable content}
Tip 1 : Try to keep only those things in resume on which you have very good command and you should be able to answer all of the questions(upto moderate level) related to your technical skills
Tip 2 : Mention your projects with brief description, try avoiding very high level description because some times reader might not be able to understand your work, keep it descriptive and understandable
