Oh My!!
Today, I am a retiree and I don't even think about working agen, But there was a time when I thought I might, just to give myself something to do while I work it all out.
This is how it went.
Previous skills and quals for which I have many but not used in the previous 5 years, no longer relevant.
Between the time of noticing a job ad that I thought that might be ok and pressing the send button, about 500 down the list in the inbox.(Pre Covid)
Don't expect a reply from more than 1 in 20 applications at all and those that do up to 6 weeks if you followed up.(Pre Covid)
Over 50, don't expect to be taken seriously.
New Australians who haven't mastered the English language are more desirable than you
As it was at the time 457 visa holders, especially in govt jobs more desirable than an Australian born qualified person new to the field.
