It depends on the facility you are in and position you are hired as.
For technicians in SATU, the engine assembly facility, they are working on 4 days on, 2 days off with alternating shifts every cycle. Morning shifts are 7am to 5.04pm. Afternoon shifts are 4.50pm (not so sure) to 2.44am. Lunch is 45 minutes and there are two unofficial 15 minute breaks.
For engineers, there are office hours, 8am to 5.33pm. There are also Lineside engineers (similar to duty engineers) which are five day cycles with mornings at 8am to 5.33pm and afternoons 5.17pm to 2.44am. They alternate shifts every week. They also work every three weekends with Friday and Mondays off.
It depends on the post you are applying for. In general, they will ask competency questions such as to describe a situation where you showed leadership, ability to communicate to internal and external parties, manage expectations and many other attributes.
The best answers are usually honest answers.
At the moment, the employee welfare is being handled by AON. Medical is reimbursed 80% on a medical flex account, generally about $300-$400 a year for a single employee with no dependents. There is also a health flex account that can be used to purchase prescription glasses, gym memberships, personal insurance, etc that is also 80% covered. Around $700 per single employee with no dependents.
Honesty and integrity above everything else. The consequence for not having these two values are very bad for an aerospace company that produces engines that 300+ lives depend on per aircraft.
