I applied via Walk-in and was interviewed in Jan 2024. There were 2 interview rounds.

Round 1 - Aptitude Test 

(2 Questions)

  • Q1. Which is muteable in python? (list,tuple,string,int,float)
  • Ans. 

    Lists are mutable in Python.

    • Lists can be modified after creation, allowing for addition, removal, and modification of elements.

    • Tuples, strings, integers, and floats are immutable in Python.

    • Example: list_example = [1, 2, 3]; list_example[1] = 5 # modifies the list element at index 1 to 5.

  • Answered by AI
  • Q2. Str="Hello world" print(str[4:8] )
  • Ans. 

    The code will print 'o wo', which is the substring of 'Hello world' starting from index 4 up to index 7.

    • The slicing operation str[4:8] extracts characters from index 4 to index 7 (exclusive) from the string 'Hello world'.

    • The index 4 corresponds to the character 'o' and index 7 corresponds to the character 'd'.

    • Therefore, the output of print(str[4:8]) will be 'o wo'.

Interview Tips & Stories

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.

  • Q1. How to implement Sqlite database in React Native?
  • Q2. What are generator functions?

    • They are memory efficient as they only generate values when needed.
