Phone Interview:
This is mostly behavioral with little introduction about my current project. Hiring manager took this round to see if I meet team culture expectations. No technical or design realted questions.

Virtual Onsite:
Round 1: System Design
Design a purchase/booking notification system. Basic requirements there should be booking.com site where customers can make booking (for ex: make a flight reservation, make a hotel room reservation, rent a car). So by assuming this three usecases. We should design a system that is able to notify vendors about the bookings made. So, if a flight is booked in united airlines vendor using booking.com flights site then our system should notify united airlines vendor.

Requirements after follow up questions:

• Vendor can have different types of notification methods to chose from. So one vendor can have SMS, another vendor can have email notification, another vendor can have a rest api exposed so for every booking rest api call should be made with the details.
