We are implementing a call center solution for technical support for our product. We have 2 existing systems:

Salesforce CRM system for sales reps, to track accounts, and contacts.
The call center system is hosted by another SaaS provider. We want customer information such as outstanding invoices (from the ERP) and account and contact information (from Salesforce CRM) to be viewable by customer support representatives when they handle an incoming call.

All question were descriptive you need to ask them input output and more detail.
My preparation:
I used to solve hackerrank problem, Its been 10 month one of my friend suggested me to try Leetcode and i started loving the platform without even having premium account, On blackfriday i purchased premium account and started preparing company wise.
Total leecode Solved: 250+ i usually repeat problem very often as i have tendency to forget.
Result:
Apart from 2nd Onsite (I screwed it because of Over-excitement) i solved all the problem optimally .
Friday 6PM got call from HR and she explained me about my feedback on all round suggested me to improve my skill on designing and discussed about what went wrong 2nd onsite round.
Got mail from HR let's stay in touch and reconnect in 10-12months.
My Success
From private engineering college to working in top investment firm to attending google interview.
In last 4 month i have attended more than 7 Interview and that one round which doesnt allow me to grab offer letter, want to overcome it.
Stay Healthy :)
