Contacted by phone saying they would like an interview. Day of interview: Spoke to day-to-day leader in the department and then head of department immediately after (possibly after getting the thumbs-up from first interviewer). After both interviews, initial interviewer returned and told me they would contact me within a few days with a decision. Contacted via phone two days later with an offer.

It is always good to go through a consultancy since the initial rounds are conducted in the consultancy and if you get through you will have to go the company directly.
