Giving a "very difficult" rating not for interview content, but because their process is just a dice roll.
I will say, my initial call with the recruiter was pleasant, professional, insightful. Good questions were asked and it felt respectful and relevant.
Not so much for the second round. Interviewer joined the call late, immediately let me know they were in a hurry to wrap up, had no idea that I was already a CSM (asked me about transitioning to this role... ??? I have 10 years experience), clearly didn't read my resume or supplemental materials (extra bummer as they require a "creative" video intro and it's obvious they don't look at them), didn't read any notes from the recruiter so it felt like a completely random new conversation, took up half the interview asking me if I had questions (??? You're leading this?), and didn't really ask anything of substance so there were very few opportunities to showcase my skills and research in that 30, now 15, minute window.
And yes, like others have mentioned, I then promptly received an email that I wasn't a "hell yes"... whatever that means. Really poor conduct for interviewing candidates and reflective of an unprofessional culture overall.
ETA: Found it super funny that their people are reposting this role now and sharing it enthusiastically across their socials. Were the hundreds of candidates that already sent in applications not enough? That speaks more to the hiring team than candidacy if you're asking for more applicants while annoying jobseekers enough that they're all roasting you on Glassdoor.
