Interview Assignment - Coop Logistics API

This repository hosts the source code for a client designed to generate a specified number of requests (N).

As part of the assignment, the candidate is required to develop an API server capable of handling these requests. The server can be implemented using either gRPC or HTTP protocols.

The primary objective of this test is to assess the candidate's ability to create a robust API server that efficiently processes incoming requests as specified by the client's operations
