Netdata interview questions

P: Are you interested in NetData? P: Salary expectations?

Deliverables: 1. The microservice written in golang 2. A brief documentation outlining your design/implementation decisions 3. A unit and end-to-end test suite for your implementation In this assignment we want you to design a new feature for Netdata cloud that allows users to receive notifications for the triggered alarms in a non-intrusive manner. To achieve that you need to create a microservice which will consume events from two topics. You will also need to create a publisher to send the AlarmDigest to the notification service. Subscribe to topics on Nats and Publish to it also. Notes 1. For the purposes of this challenge you can assume that your service will be part of an event driven system, with multiple microservices that communicate via messaging. 2. In the context of this challenge, nats will act as the message broker. 3. Our broker cannot guarantee in-order delivery of the messages 4. Our broker can guarantee at-least-one delivery for all topics 5. Your solution should be capable of handling any amount of messages 6. Your solution should be able to scale horizontally. 7. It is very important that all active alarms are eventually sent to the user, alarms should not be lost. 8. Ideally a user shouldn’t receive the same alarm twice, if its status has not changed since the last digest email. 9. Active alarms should be ordered chronologically (oldest to newest)
