IBM Software Developer interview questions

Emailed by recruiter about a week after applying asking if I was still interested. Set up a phone screen for the next week. Recruiter emailed before scheduled date to cancel and offer the link to a coding challenge instead. Recruiter never emailed the link and did not respond to follow up emails. Spoke with IBM reps at career fair and was told the position was still open and to send another email and CC'ing them. Recruiter responded saying they lost track of me. Finally sent the link to coding challenge consisting of four questions and behavioral questions all being done virtually through HireVue. I managed to answer one question but the rest were very challenging.
