Informal 30-45 minute interview, mostly consisting of information regarding the position and a few questions about my background (essentially a screen). Followed by a project/skills assessment, which took a few hours. Never heard back about the skills assessment (as of 1.5 months later) and no response from the point of contact when I asked about timeline for evaluation. Ghosting might be common – it still makes an employer look incompetent and unprofessional.
