The interview process had a first screening 30 mins chat with CEO and CPO, the founders of AMMP Technologies. Within two hours had sent me over a test in python, to build a data acquisition function, connecting to an MQTT Broker. The process took overall about a week. They came back with a negative response BUT with a thorough explanation about the reasons and with detailed comments on my code, which does not generally happens often out there. I will definitely keep an eye o other openings in the future.
