Inner join is used to combine rows from two or more tables based on a related column between them.
Inner join returns rows when there is at least one match in both tables based on the join condition
It excludes rows that do not have a match in both tables
Commonly used in SQL queries to retrieve data from multiple tables based on a related column

Find an odd occurring number among even occurring numbers.
Use XOR operation to cancel out even occurring numbers and get the odd occurring number.
Iterate through the array and XOR each element with the result variable.
The final result will be the odd occurring number.
Print the spiral order of a binary tree and matrix.
For binary tree, use level order traversal and alternate direction for each level.
For matrix, use four pointers to traverse in spiral order.
Example for binary tree: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 -> 9
Example for matrix: 1 2 3 4 -> 8 7 6 5 -> 9 10 11 12 -> 16 15 14 13
Finding pairs in an array with a given sum.
Iterate through the array and for each element, check if the difference between the given sum and the element exists in the array.
Use a hash table to store the elements of the array and their indices for faster lookup.
If there are multiple pairs with the same sum, return any one of them.
If no pair is found, return null or an empty array.
Find total number of k element with given avg in an array in minimum time complexity.
Use sliding window technique to traverse the array in O(n) time complexity.
Maintain a sum variable to keep track of the sum of elements in the window.
If the sum of elements in the window is equal to k times the given avg, increment the count.
Move the window by subtracting the first element and adding the next element in the array.
Printing non-boundary elements of a binary tree
Traverse the tree in any order (preorder, inorder, postorder)
Check if the current node is not a boundary node (not the first or last node in its level)
If it is not a boundary node, print its value
Recursively traverse its left and right subtrees

BFS/DFS question. The main catch is to identify its a graph traversal question. It would be in word problem format
I applied via Referral and was interviewed in Sep 2023. There was 1 interview round.
Plum test, basic iq test format
Bond convexity measures the sensitivity of a bond's duration to changes in interest rates.
Convexity helps investors understand how the price of a bond will change in response to interest rate movements.
It provides a more accurate estimate of a bond's price sensitivity compared to duration alone.
Higher convexity means the bond's price is more sensitive to interest rate changes.
Convexity is important for managing interes...
