Total process would be Recruiter, CIO, Panel interview, and maybe a peer SE interview thrown in there.
Expectations for this job, 1 SE to 20+ AEs. Likely expected to cover east coast to west coast time with ample coverage within those business hours. Please look at recent employee reviews and interview reviews. Maybe even reach out to prior employees. That's what I did.
Poor or lack of communication. I think of recruitment as a Sales job. You're the face of the company.
