Asked to do a Codility test involving two coding questions (in a choice of several different languages), one of which had an upper complexity bound, had a phone screen with two managers, then had an onsite at their offices in Aylesbury (Intel Security). Fairly standard stuff, non-technical first with the managers I'd spoken to on the phone, followed by an on-site coding test, followed by a QA test (look at this piece of software and identify deficiencies in it based on this functional specification).
