Zero Gravity Interview Questions and Answers

Interview preparation tips for other job seekers - When interviewer asked you to design a system (any system) , its important that we don't jump on solution immediately.

First define the problem statement and write down all requirements on paper.
Writing down the requirements and clarify the assumptions are two most important task in any system design question.

Remember nobody expects you to design fully functional auto-correct functionality, or Zomato app, or parking lot in one hour.
It took many months for any development team to get these kind of design right and sometime applications have to be redesign multiple times in reality.

In interview what people want to see is that how well you think,are you able to connect the dots in your design and can you come up with high level prototype which is generic and scalable.
I have seen people got lost in little nuances/edge scenarios which doesn't matter in larger scheme of things, so
1. Focus on big picture first.
2. Get your high level entity design, Schema Design right.
3. Then connect the dots and focus of if we can scale the system or enhance the system if required.
4. Try to accommodate any edge case scenario.

Generally, if you get first three steps rights , in one hour or so that's enough for you to crack the round.
