Q2. Sort in link List
Ans. 
Sorting in a linked list involves rearranging the elements in ascending or descending order based on a certain criteria.
• Use a sorting algorithm like bubble sort, selection sort, or merge sort to rearrange the elements in the linked list.

• Traverse the linked list and compare each element with the next one to determine the order in which they should be sorted.

• Update the pointers of the nodes in the linked list to reflect ...read more

Input:
...read more
Ans. 
Calculate the Nth Fibonacci number efficiently using recursion or dynamic programming.
• Implement a recursive function to calculate the Nth Fibonacci number.

• Use memoization to store previously calculated Fibonacci numbers for efficiency.

• Consider using dynamic programming to optimize the solution.

• Handle edge cases such as N = 1 or N = 2 separately.

• Ensure the solution works efficiently for large values of N (up to 10000).

Round duration - 45 minutes
Round difficulty - Easy

HR round that lasted for 45 minutes. Did brainstorming on puzzles and HR asked questions to know more about me.
Tips : During HR, think before you speak, they can catch any word that you speak. Prepare well for aptitude, as they shortlist less people after the test. Ask good questions during the end of the interviews. It might impress them. So prepare for it before going for the interview. Lastly, don’t be nervous, HRs are only trying to make you nervous during the interview as a part of the stress test.
