3 rounds: HR interview, simple coding interview, and managers interview. The managers interview was going well until the energy of the manager who was hiring suddenly changed, perhaps a response I gave was not to his liking. He gave the typical "I've run out of questions", and then the other manager asked questions, but later puzzlingly he had more questions. Asked for feedback after from the HR, but they didn't respond.

It was good. Four steps. Phone call, Tech, Manger and a Team. Phone call explain to you all the details and what to expect. Tech interview checks your OOP knowledge and being able to spot something, plus a leetcode task, no need working code, but working logic solution. Manager haas their own questions.
