Coding prompt and my solution: A case study on creating an Online Store Using External APIs : Printful has a solid API interface that developers can tap into in order to create white label products. Use their API to create a fully capable ecommerce store complete with cart and payment acceptance. You can partially MVP this application by creating your products using images from pngtree and upload them into your free Printful account. You don’t need a lot of products — 10 should be more than enough for testing purposes. You can also use their mock up generator to create the finished product images and an auth system isn’t required. The purpose of this project is to help you dive deep into understanding the structures of APIs, how they work and fit together on a commercial level. Printful provides a good opportunity to do this. You’ll also need to choose a payment gateway provider (i.e. Stripe or Paypal) and figure out how to take payments. Both have test sandboxes, so you don’t need real money to make your mock purchases. Just makesure the business expectation and the expected behavour from the question and ask accordingly.

Create a Reservation App with AI Features Prompt:  Project premise: Machine learning is one of the most explosive topics this year, and AI is part of the ride. Google, AWS and Microsoft Azure all have their own AI cloud services that are available for developers to dig into. Choose whichever is the most popular in your area, or simply whichever one you’re interested in, to get started. A reservation app is, in a way, like a game. You are the customer who has specific patterns of preferences — why not leverage it for increased sales using AI?Pick a bookable industry, like hotel, car rental, or restaurant, and create an application that allows you to make a reservation. Then get your AI to start making suggestions based on your patterns. Share it with your friends and test out how good it is at selling to them. You’ll also need a database to keep track of all your reservations. Using social logins will help cut down the time required for this project, but it’s not an absolute must. Alternatively, you can use Firebase’s authentication system to help cut down the development time. If you’re keen on building your own auth system and want to explore the associated concepts, then this is also a good space to do it in. You can make this one as a desktop site or mobile app. It’s a fun little exercise that is simple enough to boot up, but complex enough to be noticed by potential employers.

The Painter’s Partition Problem using Binary Search:
Given are N boards of with length of each given in the form of array, and K painters, such that each painter takes 1 unit of time to paint 1 unit of the board. The task is to find the minimum time to paint all boards under the constraints that any painter will only paint continuous sections of boards, say board {2, 3, 4} or only board {1} or nothing but not board {2, 4, 5}.We can fix the possible low to high range for the target value and narrow down our search to get the optimal allocation.We can see that the highest possible value in this range is the sum of all the elements in the array and this happens when we allot 1 painter all the sections of the board. The lowest possible value of this range is the maximum value of the array max, as in this allocation we can allot max to one painter and divide the other sections such that the cost of them is less than or equal to max and as close as possible to max. Now if we use x painters in the above scenarios, it is obvious that as the value in the range increases, the value of x decreases and vice-versa. From this we can find the target value when x=k and use a helper function to find x, the minimum number of painters required when the maximum length of section a painter can paint is given.

My interview motioned upon, data mining and business intelligence. Post which, my projects were questioned upon machine learning. An interactive quintessence was laid for data science and enrichment of algorithms. Also, emphasizing were upon reinforcement learning was pretty much in case. A lot of emphasis were given on supervised learning of machine learning. So, brace yourself and keep acquitted with latest edge of technology and revise your projects religiously! Although, apriori algorithms entailed a real time monitoring systems of Amdocs use case study itself.  Was asked questions on titanic survivors from my project of machine learning and the in's and out's through algorithms. Next up, questions were raised from my research paper. Future outcomes and working ( methodology of the research paper was questioned upon.Tip 1: Work on resume building and skills mentioned on itTip 2:  Try building use cases when coding problem arise only then go ahead with your solution. Tip 3: try to work down all test cases as in our of 10 try to succeed in all 8 test cases successfully!
