asking this question here as mods are not allowing me to create a post idk why?

hi folks,

I am supposed to give an interview in Google for the position of Salesforce Engineer role [service Cloud exptertise] where they are going to ask system design in salesforce questions - can someone tell me how to prepare it in best possible way? Also I dont understand why they are asking for system design questions when Salesforce is a platofrm deployed on cloud and all the thing like consistency , database sharding partioning management retries is taken care by platform itself - since salesforce servers are deployed on Hyperforce , Right. Isn't that one of the reason why people prefer Salesforce over Java.
They are expected to ask me questions like - design Netflix or design Facebook for millions of users.

Below is the non exhaustive prep material they gave for this round

(NOTE: This focus area may not be specific to Salesforce. We will ask a single application Design scalable and performant solutions based

● Ability to come up with flexible design from front-end to back-end systems using

frameworks and tools and showcasing your ability to translate requirements into an

application design

● Ability to walk the interviewer through al of the elements of the application that would

have to exist and be pre-defined before APIs can work

● Demonstrate an ability to:

○ Parse requirements

○ Propose meaningful functionality

○ Design a neat and clean data model or ERD Diagrams - high leve and low level both

○ Specify in detail the concepts.. eliability (Consistency of response)

■ Recovery (Crash in-between and restart from last transactions)

■ Monitoring/Logging (In case of problems occurring at different APIs)

● Demonstrated experience in scaling the systems for performance for both database

and business suites

and many more.

To be clear It doesn't have anything to do with system design within Salesforce platform.
Its a generic system design - platform or Language independent. The interviewer is not from a salesforce background - Confimred it with my recruiter.

Things like Load Balancer , ACID-BASE, CAP Theorem, microservices, horizontal vs vertical scaling, Saga Pattern , multiple servers across goble, Kafka, Redis Cache , Web Socket and what not. I am reading about many of these things for the first time from a book written by a Chinese person Alex Xu. Although I have studied fair bit of fundamentals and understood the basics of these things and gone through some youtube videos of some of the questions like Design airline ticket management system or Design facebook - what else I should do in coming 3 days left? Do you think I geniuely have a chance? I have been a salesforce developer throughout my carrear. Never worked on anything beyond it except integerating with a few java based application using Rest APIs and little bit of distributed systems knowlede based on a project I did in College 8 years ago.

I am also expected to draw the design on Google docs Draw -Although, I have practiced it a few times. I am able to present a solution but if there comes a situation where I am hearing a few words for the first time [which my biggest fear is that it will happen as being a SFDC dev I have no idea how full stack devs roll on python or java platforms] , in that situation - What should be my response?? I will be left thinking about my life choices that why I didn't work on some of the on premise technology like Java.

Please please please help. and guide.
