• The timing was distributed Questionwise.

ROUND 2: Interview (Technical)

The interview started with my introduction followed by questions:

• CODING:
  1. Printing Star Pattern
  2. Design a dictionary to store the frequency of the elements present in a string
  3. Code to find whether a string is Palindrome or not
  4. Concatenate one string and integer
• DBMS:
  1. SQL query to find the nth highest value
  2. What is left to join
• PYTHON :
  1. How to traverse the string
  2. How to reverse a string using multiple ways
  3. How to represent an element having no value
     • What is NONE?
     • Is it a value?
     • How does NONE differ from BLANK and 0?
  4. Difference between tuple, list, and dictionary
  5. How we define a class and its constructor in Python
  6. What is the benefit of Python being an interpreted language?

ROUND 3: Final Interview (HR + Technical)

The interview consisted of HR-based questions, as well as technical questions related to Projects, Coding, and Logical reasoning. It was a 40-45 minutes long interview. It started with some basic questions like :

1. How are you?
2. Brief intro?
3. Why have you opted for computer science?
4. Why did you switch so many languages?
5. Why Python?
6. If you get hired, will your college allow you to work or you will be provided with NOC?
7. Do you like to work from home or office?
8. How would you score yourself in Python out of 5?
9. Tell me about your experience in IEEE (a society in our college which I have mentioned in my Resume).
10. Any current offer?
11. Salary expectation?

Then the interview shifted towards my Python projects in detail.

1. Tell me about the Python project i.e. Web scrapper that you have mentioned. How many members were in the team and what was your role?
2. What challenges did you face while scrapping data? How can you resolve them?
3. The interviewer gave me different use cases regarding scrapping data and asked me to give a solution for it :
   • When you scroll more information will be there and you want to scrape that data based on the filter applied; How this crawled-down event will be triggered?
   • What will you do if your IP is blocked after parsing a page for a long time?
   • You are on a particular page and when you click on a particular button, that request is sent to the server, Then from there we get the data(suppose email and contact number) now you want to scrap this information. How will you do this?
4. Can you tell me more about your final-year project? and what is your role?

The interview also asked me to write a code for :

• Printing start pattern; also try to optimize it (followed with some cross questions like complexity and logic explanation)

I was also asked a few logical reasoning-based questions at the end:

1. There is 1 bike with 2 wheels and 1 spare wheel, each wheel can cover 5 km. Then what is the maximum distance that you can cover in the given scenario?
2. What is the case of a car having 4 wheels and 1 spare wheel?

I was also asked to rate myself in MYSQL out of 5? and how much time will I take to reach 4 out of 5.
