I received an e-mail asking for more information and times for an initial interview. Someone from HR reached out saying it may take a while since this was during the end of year/holidays but then never responded to any further e-mails.

Hiring manager interview. Classical interview with background talk and also explanation of job expectations. Interviews with 5 engineering managers. Each manager tries to understand how my background fit the their expectation. Another interview with Electrical Engineer manager / director.
