Interview Preparation Tips

Interview preparation tips for other job seekers - Don't trust Ankercloud. Everything is fake. Whether it is interview, salary discussion, their location, HR, higher authority, etc. Everything is fake. Only the thing at which they are best is "SHOW OFF".
Firstly they said "we are very impressed by your performance in all technical and HR rounds so please don't apply anywhere else." They gave me the date of joining on email conversation but didn't release the offer letter. They started postponing the joining date for 2 months and after 2.5 months, when I started conversation again with HR, they said "we are hiring TL first, after that we will let you in". Finally after 3 months, again when I reached to them they said "we can't hire you". The thing is they are not even bothered to contact you...
Please be aware of the fraud. Don't fall into the trap.

  • Q1. Implement Merge Sort.
  • Ans. 

    Merge Sort is a divide and conquer algorithm that sorts an array by dividing it into two halves, sorting them separately, and then merging the sorted halves.

    • Divide the array into two halves

    • Recursively sort the two halves

    • Merge the sorted halves

  • Answered by AI
  • Q2. Given a BST containing distinct integers, and a number ‘X’, find all pairs of integers in the BST whose sum is equal to ‘X’.
  • Ans. 

    Find pairs of integers in a BST whose sum is equal to a given number.

    • Traverse the BST and store the values in a hash set.

    • For each node, check if (X - node.value) exists in the hash set.

    • If yes, add the pair (node.value, X - node.value) to the result.

    • Continue traversal until all nodes are processed.

  • Answered by AI
  • Q3. Given a set of time intervals in any order, merge all overlapping intervals into one and output the result which should have only mutually exclusive intervals.
  • Ans. 

    Merge overlapping time intervals into mutually exclusive intervals.

    • Sort the intervals based on their start time.

    • Iterate through the intervals and merge overlapping intervals.

    • Output the mutually exclusive intervals.

  • Q5. Implement AVL Tree.
  • Ans. 

    An AVL tree is a self-balancing binary search tree where the heights of the left and right subtrees differ by at most one.

    • AVL tree is a binary search tree with additional balance factor for each node.

    • The balance factor is the difference between the heights of the left and right subtrees.

    • Insertion and deletion operations in AVL tree maintain the balance factor to ensure the tree remains balanced.

    • Rotations are performed ...

    • If not, then try to find the minimum number of squares required for the remaining number.

    • Repeat the process until the remaining number becomes 0.

    • Return the minimum number of squares required for the given number n.

  • Answered by AI
  • Q7. Insertion sort for a singly linked list.
  • Ans. 

    Insertion sort for a singly linked list.

Interview Preparation Tips

Round: Test
Experience: There were 2 coding questions (no penalty for wrong submission) and 20 Multiple Choice Questions(with negative marking). We were given 90 minutes to solve them. MCQs were based on Data Structures, OS, CN, C outputs, OOP etc.
Tips: Experience in Competitive Programming might help in solving coding questions. No constraints were mentioned and detailed Instructions related to problem were stated vaguely. So code carefully.
Duration: 1 hour 30 minutes
Total Questions: 22

Round: Technical Interview
Experience: The interviewer asked me to introduce myself and a brief introduction of the projects that I have done. She first asked me questions related to my project. After that she moved on to the data structures part.
Tips: Take your time to approach the problems and if the question is not clear ask the interviewer to explain it again.

Round: Technical Interview
Experience: The interviewer asked me about how my previous round went. After that, he asked me to introduce myself and a brief introduction of the projects that I have done. He first asked me a few questions related to my project. Then he moved on to the data structures part. In this round the interviewer gave me strict time limit for coding the solution on paper for each problem and as soon as I was done coding he gave me 2-3 minutes every time to find errors and debug my code.
Tips: Do not panic even if the interviewer sets time limit while solving problems. If the question is not clear ask the interviewer to explain it again.

  • Q1. Simple linked list questions-find middle element,given a pointer to second last element delete it
  • Q2. Explain insertion sort,quicksort
  • Ans. 

    Insertion sort and quicksort are sorting algorithms used to sort arrays of data.

    • Insertion sort: iterates through the array and inserts each element into its proper position.

    • Quicksort: selects a pivot element and partitions the array into two sub-arrays, one with elements less than the pivot and one with elements greater than the pivot.

    • Insertion sort is best for small arrays, while quicksort is best for large arrays.

  • Q5. Merge two sorted linked lists using recursion
  • Ans. 

    Merge two sorted linked lists using recursion

    • Create a recursive function that compares the first nodes of both lists

    • Set the smaller node as the head of the merged list and call the function again with the next node of the smaller list

    • Base case: if one list is empty, return the other list

    • Return the merged list

  • Q6. Given an integer(consider 4 bytes) find which byte is zero
  • Ans. 

    Given an integer, determine which byte is zero.

    • Convert the integer to a byte array using bitwise operations.

    • Iterate through the byte array and check for a zero value.

    • Return the index of the zero byte.

    • Consider endianness when converting to byte array.

  • Answered by AI
  • Q7. Program to check whether your machine is little endian or big endian
  • Ans. 

    To check endianness, create a 4-byte integer with a known value and check the byte order.

    • Create a 4-byte integer with a known value

    • Check the value of the first byte to determine endianness

    • If the first byte is the least significant, the machine is little endian

    • If the first byte is the most significant, the machine is big endian

  • Q8. Print something before execution of main()(use static objects)
  • Ans. 

    Static objects can be used to print something before main() execution.

    • Static objects are initialized before main() execution

    • They can be used to print something before main()

    • Example: static int x = printf("Hello World!");

    • Output: Hello World! will be printed before main() execution

  • Answered by AI
  • Q9. Memory allocation for static varibles(when,which segment etc)
  • Ans. 

    Static variables are allocated memory in the data segment of the program's memory space.

    • Static variables have a fixed memory location throughout the program's execution.

    • They are initialized to zero by default.

    • If initialized explicitly, they are stored in the data segment.

    • Static variables can be accessed by any function in the program.

  • Answered by AI
  • Q10. Find space and time complexity for a recursive function(he wrote it)
  • Ans. 

    Finding space and time complexity of a recursive function.

    • Space complexity is the amount of memory used by the function.

    • Time complexity is the amount of time taken by the function to execute.

    • Recursive functions have higher space complexity due to the call stack.

    • Time complexity can be calculated using Big O notation.

    • Examples of recursive functions include factorial and Fibonacci sequence.

  • Answered by AI
  • Q11. Some questions on major project
  • Q12. Preprocessor directives,volatile keyword
