How should one approach System Design questions during an interview?

Here's the step by step guide:

🧵👇🏻

System design interviews are generally open ended discussions. There's no one right answer.

The main focus in this round is to see your thought process and whether you'll be able to design a minimal system keeping future scale in mind and by following the standard principles.

Know that many interviewers deliberately make it hard to see how you approach a given problem.

You cannot possibly design a complex system in 1-2 hours which engineers usually take months to years to design, develop and build.

So this is how you should approach this round:

1. Clarify the requirements: As mentioned earlier the questions are generally very open ended. So you need to ask a lot of question to set the scope clear for the discussion.

Example: "Design an application like Twitter"

Twitter has a lot of features like:
- Post tweet
- Home timeline
- Profile timeline
- Analytics
- Likes
- Retweets
- Following
- Bookmark
- Trending etc

You get the idea!

Facebook -- having taken out full-page ads in the NYT, Washington Post, and WSJ -- is generally seen as the primary victim of the new app privacy controls coming in iOS14. But Google is perhaps even more vulnerable to ATT. Why has Google remained silent? (1/X)

2/ First, background: here's a high-level overview of how ATT / IDFA deprecation impacts advertisers and ad networks, and why this whole ordeal has put advertisers and ad networks into a state of panic:

3/ Google is equally as susceptible to harm from ATT as Facebook. Google's UAC product -- esp its tROAS and tCPA campaign objectives -- relies as much on IDFA-indexed monetization and engagement data as FB's mobile product does. But Google has one big weakness wrt ATT: YouTube

4/ Broadly, view-through attribution accounts for a disproportionate % of conversions from YouTube app install impressions. This means: user sees the YT ad, doesnt click, downloads app later, & Google is able to claim it by reconciling IDFA seen at impression to IDFA seen in app

5/ View-through attribution is nonexistent in the ATT paradigm as it relies on the IDFA; some significant portion of YT's attributed conversions will evaporate. So why isnt Google vocally opposing ATT? Two reasons: consumer optics and its duality as ad network / mobile platform
