Hey,

Recently I encountered a question in an interview for HLD round, even though I created architectural diagram and specifying requirements, the interviewer wasn't satisfied and he rejected me. Hence I am curious to know what could be the possible solution for this.
Here is the question:
"You are running a dining restaurant of 100 tables. You have replaced all the waiters with robots. Design a system keeping only dining in mind."

For the question. I will start with how people will come to the restaurant.
How many dishes will be on the menu?
Are there chances of dish unavailable in specific time?
How many times customer will call the bot for ordering a menu?
Will the menu elements will be fixed?
Is billing included in the system?
Are reserving tables included in the system?

Etc....

like

I would really appreciate if there are any references for this problem

What was your approach and architecture ?

Happened with me too. But, Later I understand I should have asked more questions. Like frequencies of data.
System design is all about converting requirements to tech. I have seen a lot of people rejecting candidates. Because, They jumped into the solution by assuming requirements rather than asking questions.
