I can’t tell you much from an engineers perspective but from a pilots view, it’s a pretty abismal place.
The people you work with (crew/cabin crew/engineers) on the whole are fantastic. However the decision making of management can leave a sour taste for the troops on the front line.
There a hundreds of va pilots applying for qf. The money and progression seems far better there. Qf also seem to have a seniority system that works. Pilots on the ATR are trapped on the fleet for at least 10 years from joining and 777 s/o’s are also frozen for about 3 years. Meanwhile the company will go ahead and bring in new hires off the street on better fleets(737)/pay/bases and wonder why people are disgruntled and leave...
Also Qf management sound like they are kicking goals while the VA management team is losing friends at air NZ and undoing years of good work.
It all depends on what you are after. If you prefer security and probably better pay, I would stay at qf. Va is definitely a shakier ship but if you are after a change of scenery, it could also be the right place for you.
