I took a break from a big tech and joined a startup. It was infuriating how people were actively opposing my TDD approach. It was redeeming when I was shipping one of my projects (service for integration with 3rd party) - and product managers and others were expecting we will need weeks to test and fix the bugs - but instead the other party just said "it's perfect, no comments". All because I was "wasting my time" on writing "useless tests" that helped me identify and discuss edge cases early in the process. Also, I could continue working on parts even while waiting for a response from product managers or while DevOps were still struggling to provision the resources.
