Reading Time: 2 minutes So this would be new set blog post and my videos on LetsDoCoding. In this particular post we shall be discussing shortly a very simplistic and bare minimum Solution Design for URL Expander and Shortner Service, very similar to Bit.Ly. I have asked this question in quite a few Interviews I have taken in the Initial interview rounds and this post covers all the aspects.
Cloud based solution design.
Deployment Strategy and replication for better UX
Services and Contracts Design
Database and ER Model Design.
You can refer the video on youtube for complete details, but we shall be discussing some pointers in this post. This question is targeted for interview questions and discussions on system and solution design. So Lets Begin
Reading Time: < 1 minute What would happen if you need to implement two interfaces with same member names. How would you do it. While this question seems simpler, its not actually in implementation as there are a few hidden tricks. In this video we try to cover the basic fundamentals of the Explicit Interface Implementation and also do a quick hands on how to do it.
