End May: Applied for a position with a ministry the last day before posting closed
End May: Shortlisted for an interview the next working day + asked to finish a written test and submit within 12 hours from my preferred day
First week of June: Attended interview with SD, SAD, D and a HR BP the week after posting closed.
First week of June: Received another email and WhatsApp from another team asking for an informal chat about myself and the work they do for the second week
Second week of June: Attended interview and team seems pretty pleased. HR was not present in this session. Was told at the end that they will liaise w HR BP but have not heard anything from HR on waiting time, application procedure since. Have followed up with HR on this matter but did not get a response at all.

Do I need to be worried? The second interview felt rather good to me though.
