The question plot was, there were two tables: Customers and Orders which are linked to each other via a foreign key.
- Get the list of customers who has more than 1 orders.
- Get the top 3 orders in terms of amount.
- Get the list of all unique items.

You are given an array 'arr' of length 'n', consisting of integers.

A subarray is a contiguous segment of an array. In other words, a subarray can be formed by removing 0 or more integers from the beginning and 0 or more integers from the end of an array.

Find the sum of the subarray (including empty subarray) having maximum sum among all subarrays.

The sum of an empty subarray is 0.

Example :

Input: 'arr' = [1, 2, 7, -4, 3, 2, -10, 9, 1]

Output: 11

Explanation: The subarray yielding the maximum sum is [1, 2, 7, -4, 3, 2].

You have been given a binary tree of 'N' nodes. Print the Spiral Order traversal of this binary tree.

For example

For the given binary tree [1, 2, 3, -1, -1, 4, 5, -1, -1, -1, -1]
    1
   / \
  2   3
     / \
    4   5

Output: 1 3 2 4 5

You are given an array of integers, 'PRICES' of size 'N', where 'PRICES[i]' is the price of a given stock on 'i'th day.

On each day, you may decide to buy and sell the stock. You can only hold at most one share of the stock at any time. However, you can buy it and then immediately sell it on the same day.

Return the maximum profit you can achieve.

Note: You can't sell a stock before you buy one.

Example:

Let's say, 'PRICES' = [7, 1, 5, 4, 3, 6]

Purchase stock on day two, where the price is one, and sell it on day three, where the price is five, profit = 5 - 1 = 4.
Purchase stock on day five, where the price is three, and sell it on day six, where the price is six, profit = 6 - 3 = 3.
Total Profit is 4+3 = 7. Hence we return 7.

What is Polymorphism ? Types of Polymorphism ?
What are Overloading and Overriding? and main difference between them.
What is Abstraction?

What tech stacks I have used so far and in which domain I am more inclined ?
I told him that I have worked on the Backend and am also inclined to work on the backend side.
And the last question was,
Why Tekion? I answered that pretty well I guess.
