I submitted my resume, cover letter, website, and a quick paragraph of what UX design means to me. I was asked for a phone interview a week later with a senior UX designer. The phone call was quick and brief, with pretty standard questions. During the phone interview, the senior UX designer offered me a 2-day design challenge, of which she sent the brief to me two days before the scheduled 45 minute remote presentation. I worked really hard on the design challenge and went above and beyond what was asked for, but my interviewer (same as the phone interviewer) seemed pretty disinterested during the presentation. There wasn't much feedback, but I didn't end up getting the job without knowing a particular reason like lack of thoroughness or any other big problems.
