My procedure was a bit particular, since I had first interviewed for another position which was eventually given to an internal candidate. During this first interview stage I had 3 interviews: 1) hiring manager 2) HR recruiter + director 3) internal stakeholders, HR manager, hiring manager (including business case).
Afterwards, I got contacted by Lineas to interview for another position. This interview stage consisted of 3 interviews: 1) hiring director and hiring manager2) again hiring manager 3) future team member. No tests or assessment day.
