Clarification Questions Understanding of Hotel Are we also including Airbnb, lodges or only hotels? [Only Hotels] Which geography are we talking about? [Bangalore] Overall Approach Define the area of Bangalore that will be around 600Km². Since there is a national park, a lot of lakes, forests, and wetlands so assuming that around ~50% of the area is there where a potential hotel can reside. So we are looking around an area of 300Km², we can divide this area into 3 parts according to the density, assuming a normal distribution of 25% highly dense for the hotel, 50% mid dense and the rest 25% is low dense. For highly dense that is closely around 75km², for a Km² we can have 5 hotels, that is around 375 hotels. For mid dense(150Km²), on an average, we have around 2.5Hote

Shailesh:  Before that, let me clarify my understanding of listening to music on Youtube.  Y outube has two applications where a user can listen to music, one is normal Youtube, and the other one is launched exclusively for music called Youtube Music. People use Youtube because it is easy to search, it’s an extensive list of songs, and they can see the video.

  URL Shortener URL shortener is the way by which we can reduce the size of the big URL into a smaller one and clicking on the smaller URL will take you the original one. The smaller URL is easy to share and doesn’t occupy much space. It is very useful while doing some tweets. Design Requirement Functional Requirement URL shortener should be able to shorten any URL given to it, and it should be unique alias of it. When the user clicks on the shortened link, the user should get directed to the original link. The user should be able to define the time till which it is available. Non Functional Requirement The availability of the system should be high because if our system goes down, then all the URLs will start failing. URL should be available in minimal time; minimum latency should be there. The URL shouldn’t be predictable. Capacity Estimation We can assume that for every URL shortening service, there would be 100 reads. So basically, there would be a 100:1 read/write ratio to the syst

Alexa is a virtual voice assistant that helps people seamlessly organise their lives by getting the information from the web, adding items to the Amazon shopping cart, or helping with home automation. Is the broad understanding of Alexa correct? Interviewer:  Yes, that’s okay. Shailesh:  Okay, now I have so m e questions that I want to clarify; my first question is, what is the objective of improvement? As per my understanding of the question, we are trying to improve the user experience and make it more engaging, want to increase the cart value, or reduce the time taken by an individual to buy the item. Is that correct? Interviewer:  Yes, correct. We can go ahead with this goal of reducing the time taken by the user to buy the item on amazon. Shailesh:  Alright, are
