5 interviews; 2 with HR, 2 with team members, and final with executives.
The HR interviews were straight forward HR type interviews, most likely to make a baseline assessment of cultural and experience fit. The team member interviews were a mix of collegial and technical; mos tlikely to affirm cultural fit and technical competence. The final interview was by far the hardest, a true drill down into past achievements and technical knowledge; in particular the CTO drives deep and hard into the limits of your technical knoweldge; searching for scope and consistency.
