Fast-tracked to face-to-face interviews after placing in a programming competition - had two rounds that were technical focussed, the second was with a more senior engineer and involved a conversation about the role / my experience - at this point it turned out that the areas I were interested in (and that had been advertised) weren’t actually accepting interns, and the remaining roles weren’t a good fit so I was rejected. Possibly just because it was a busy hiring time, but the response times from HR were a lot longer than what I’m used to (think 2 weeks, sometimes after their suggested next interview date).

Got an email to schedule a phone/coding interview using Hackerrank. Phone interview questions weren't that difficult, my questions only involved working with basic arrays. After passing I got invited to an in-house interview at their office in London.
