Familarity with tech stack, work experience and salary.

The hiring manager asked me to do an OOP solution for a warehouse inventory system, where you need to track the type and amount of a product and find the nearest warehouse with products the customer is looking for. Despite this being an OOP and you being able to implement it in TypeScript or any language, and despite the HM not mentioning, your solution needs to handle concurrency and have locking. Then you’ll be asked what you’d do differently in a production environment. You’ll need to state the obvious like writing tests, using a DB, distributed locking etc. The way they asked the question was very silly and assessed nothing.
