Interview Preparation Tips

Interview preparation tips for other job seekers - Not at all good experience. Looks like the structure is baffled now after pandemic hit. First of all HR people, they have so much attitude that you can't even ask them any query regarding your JD or project. Secondly there are many rounds but it all depends upon the interviewer mood only and only. Because you are not hired for a direct project, so if the interviewer is egoistic and high attitude, then it's difficult to get positive feedback even if round well all well. Disappointing experience. Suggestion would be to put right people for talent selection. If people are kept in similar way, every new candidate might have negative experience.

  • Ans. 

    Find the equilibrium index of an array where sum of elements on left equals sum on right.

    • Iterate through the array and calculate the total sum of all elements.

11 Questions

  • Q1. What is the difference between C and C++?
  • Ans. 

    C++ is an extension of C with object-oriented programming features.

    • C++ supports classes and objects while C does not.

    • C++ has better support for polymorphism and inheritance.

    • C++ has a standard template library (STL) which C does not have.

    • C++ allows function overloading while C does not.

    • C++ has exception handling while C does not.

  • Answered by AI
  • Q2. What is the difference between for and while loop?
  • Ans. 

    For loop is used for iterating over a sequence while while loop is used for iterating until a condition is met.

    • For loop is used when the number of iterations is known beforehand

    • While loop is used when the number of iterations is not known beforehand

    • For loop is faster than while loop for iterating over a sequence

    • While loop is useful for iterating until a specific condition is met

    • For loop can be used with range() functio...

  • Answered by AI
  • Q3. Write a program to add two numbers without using + operator
  • Q4. How to you reverse a string without using any looping and inbuilt functions?
  • Ans. 

    To reverse a string without using any looping and inbuilt functions, we can use recursion.

    • Create a function that takes a string as input.

    • If the length of the string is 0 or 1, return the string.

    • Otherwise, call the function recursively with the substring starting from the second character and concatenate the first character at the end.

    • Return the reversed string.

    • Example: reverseString('hello') returns 'olleh'.

  • Answered by AI
  • Q5. How many queues will you use to implement a priority queue?
  • Ans. 

    A priority queue can be implemented using a single queue or multiple queues.

    • One approach is to use a single queue and assign priorities to elements using a separate data structure.

    • Another approach is to use multiple queues, each representing a different priority level.

    • For example, if there are three priority levels, three queues can be used to implement the priority queue.

  • Answered by AI
  • Q6. Which datastructure would you use to implement an heteregenous array?
  • Ans. 

    An array of objects can be used to implement a heterogeneous array.

    • Each element in the array can be an object that represents a different data type.

    • The objects can have different properties and methods based on their respective data types.

    • For example, an element can be an object representing a string with a 'value' property and a 'length' method.

  • Ans. 

    The missing rupee is not actually missing. The calculation is misleading and does not account for the total amount paid.

    • The initial amount paid by each person was Rs.10, totaling Rs.30.

    • The owner gave them a discount of Rs.5, so they paid Rs.25 in total.

    • The broker took Rs.2, leaving them with Rs.23.

    • When the broker returned Rs.1 to each person, they each received Rs.1 back, totaling Rs.3.
