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.

  • 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'.
