Sometimes workload can get the better of you, but unless you ask for help it won't magically appear - this is just common sense really - your supervisor/manager is there to help, and are always willing to.
Occasionally you may go to lunch late or leave a little late if you get stuck on a support call with a customer, however as it's round the globe 24/7 support you can always hand the case over to the next engineers on shift.
Benefits package is reasonable - nothing amazing but good compared to other companies!
