I applied online. Heard back within the week and had an initial interview with hiring manager. It was a video call and went relatively easily, spoke about my experience and I asked questions around process, product and the team. I was told a few days later I'd progressed to the case study stage. Spent a fair bit of time studying and analysing a product and coming up with recommended improvements. The presentation call was short, done with the hiring manager and a senior member of the engineering team. At the end of it they concluded their questions had been answered in my presentation and a few days later I was invited to the final stage interview: what they called a cultural and depth of expertise interview. Then, silence. I followed up twice to schedule the final interview and left it at that. Any company / manager that would show so little respect for a candidate's time (ghosting after extending an invitation to another interview) is not worth it.
