Yes they are interviewing.
1st year FO on 320 is $139500, after 1 years service (if you have an ATPL) it jumps to $156,000. From there it increases by about $5000 per year plus CPI inflation plus 0.8%. Tax free allowances are approx 20/30k pa.
1st year SO $124,400 then $139,000 after a year. Allowances 30/40k pa.
On top of the salary is incentive pay. This is variable between fleets and domiciles. But any hours over 60 per 28 day roster your salary is multiplied up to 100hrs.
At the moment on the 320 its about 15% (approx 70 hrs) times your salary and SO are 25% (approx 80hrs) times your salary. Very rough and variable but just an idea of how much you’ll earn.
