Wearecrane interview questions

Applied for their position for part time on LinkedIn, got a Whatsapp message asking for an interview. However, the person interviewing me was already tendering her resignation and passed my contact to another member of the staff. Till now, I have not received any word for onboarding, events, work, etc. Unprofessional, lack of follow up and it has been months since my "contact was passed to another staff member."
