Initial 1:1s with recruiter and department head, then in-depth case study review, then ~4 1:1s across the different folks who sat in the case study review. The recruiter let me know via email that they went with a different hire

Was contacted by email to schedule a phone interview, and once scheduled I felt confident. When the interview arrived, and I picked up the phone, I was greeted with "I can't find your resumé" and "I don't know what the hiring manager is looking for, let me pull up the job description." Thrown off guard, we went line-by-line down the requirements, and they just asked me to respond with my relevant experience. Keep in mind, I wasn't contacted by a 3rd party recruiter, I was contacted by SoFi's SENIOR technical recruiter. Nevertheless, this went on for about ten minutes before they stopped me mid-sentence to say, "I'll ask the hiring manager to see if you can continue the process because you check all the boxes but one." Then hangs up. About 5 hours later, a call: hiring manager. "Are you willing to relocate?" "When will you have your degree?" My responses made them comfortable and they scheduled an in-person. Once the in-person was scheduled, "You know what, we are going to go with other candidates" and hangs up. HOW UNPROFESSIONAL! Then another 2-hours later, the formal rejection email arrives.
