RED FLAG, RUN: They Ghost, that's a big red flag and cultural misfit, if they don't respect basic cnadidate time an effort after going through 4 stages of interview:
Stage 1: Screening with Recruiter
Stage 2: Interview with Hiring Manager
Stage 3: Task
Stage 4: Presenting Task
Stage 5: Ghosting. Have read this in another interview review for Hambi media as well. Essentially the same company and recruiter.
