re: I am applying for front end dev but the interview will have one hour of "scaling web app", what does it involve? VIEW POST


They will most likely present you some random case of a web app that has hit scale. Ex. pages load slowly, network connections start timing out and your servers are starting to creak under heavy load.

Since you are applying for front end role, you will be asked to discuss how you can use catching (browser vs CDN) and their roles of static and personalized content, differences between centralized and high latency components, the principles of CI & CD and how you would implement them, the importance of TDD, how 'X' design pattern could make massive code base more maintainable, etc.

They are not looking for A-Z solution on the site. They are looking for your initial thought process, the initial steps you would take if you would tackle the presented case tomorrow.
