I received an email from the technical recruiter with invite to talk about the job opportunity, it was a 15 minute call where I heard of the company and the role and spoke about myself. Following that call I had 4 interviews with the hiring manager and team members - all were about my experience and checked my fit to the role. At the end of the process I had an interview with the CEO where we talked about motivation, goals and vision of the company and me as a contributor.
