Did you work on any projects before getting the ML job? i try to learn by myself but never seems to me any employer would hire me on the basis of doing online courses. So how did you end up crossing that gap?
* reproducing model training * deployment of experiments in a CI/CD pipeline * observability of models * discoverability and governance of results * versioning of data / models * optimizing for latency vs throughput * when to use batch vs real time etc
Just like a course in a computer language wouldn't necessarily teach you about CI/CD, horizontal vs vertical scaling, or domain-specific bits.
