It was a rather disappointing experience. I had 2 phone interviews which went well so they flew me in for an onsite. Having performed well on not just one but two interviews felt more than just luck - I felt confident that my skill level should be reasonable for the onsite. This was not true at all. The difficulty of the onsite algorithm questions was just way higher than on the phone. They actually cut the interview series short - just after the first prompt. I don't understand why the phone interviews were made so easy if that's not the level they require for interns. I flew from Canada and missed classes for this - interviews are usually a learning experience regardless of how they go but this was just so disappointing, I left completely in tears. At least they fed me lunch before declaring my skill level so shittу that there was no point continuing interviews.
