Dynamic Planner interview questions

1. Reached out to one of HR team. 2. Was introduced to a Director. 3. Spoke with Director over a Whatsapp Call 4. This Director shared a job role which another Director was hiring for and asked for a Teams Chat. 5. Conducted a Teams chat, and was told it may take up to 3 weeks to get back to me as they are busy interviewing. 6. I have then had to chase the Director for an update to find they have offered the role to someone. Would it not be courteous to not mention to other candidates if you are not progressing them rather than having the candidate chasing you.
