Interview design questions

System design interview questions can be quite open-ended, which is why many people are afraid of this kind of interview. Although working experience plays an important role in system design interviews, it doesn’t mean that nothing you can prepare for.

We Gainlo team have manually selected a collection of popular system design interview questions and provide in-depth analysis. As you know that even for the same question, different interviewers can make the interview totally different. Therefore, please don’t take our posts as something like standard answers, instead, we want to use them to give you tons of ideas about how to analyze different problems and reduce your stress about system design interviews.

Many problems we chose are both practical and interesting. For instance, in the post How to Design Twitter series, we’ve covered a wide range of topics including search, ranking, recommendation, scalability and so on. I’m pretty sure you will learn a lot from our posts even if you are not preparing a system design interview.

I don’t think there’s any golden rules to ace interviews that work for everyone. However, if you’d like to put enough time and energy into practicing with system design interview questions, you will eventually find them quite easy for sure.
