Applied for their winter internship in August.
Was sent a code sample/challenge immediately, along with a survey asking many behavioral-type questions. The coding challenge was fairly easy.
A few days later, I was contacted about scheduling two back-to-back technical phone interviews, which I completed two weeks later. The first one was much harder than the second, though I don't think this was coordinated.
Make sure you get a working solution (though they don't try or expect your code to compile), even if it's just brute force.
Three weeks later, my application was approved by the hiring committee, and I was sent the winter 2019 host matching form. Because I was fairly early in the process, projects were still being approved, and it was four weeks before I heard back from anyone. Had a non-technical host interview within the week of hearing back, and an offer later that day.
