Do you think its a bad sign that some of us haven't heard anything whereas others have already completed online testing?
Not necessarily but can't say for sure, processed in batches - probably, insufficient resources allocated to task - possibly, more applicants than estimated - unlikely.
Properly done RPL/TNA processes take much longer than most people think.
Properly done interviews take a while to arrange, (time zones), do and write up.
I think you need to ask yourself - how well did you meet the selection criteria?
Very well? then you shouldn't worry.
Well? then a little worried.
Not so well? then more worried etc.
For Sydney TCU.
Worked high capacity environment?
Worked parallel runways?
Worked Eurocat?
Then I wouldn't been too worried.
Worked ENR non-radar, remote Tower, small TCU. Only got your rating this year or been rated for 35 years?
Then I'd be worried (sorry).
From an organisations' point of view, better to do the recruitment process correctly vs rush it and get it wrong. Bad for the individual, bad for the system, bad
PR/IR.
Recruitments take significantly longer than most applicants think...
