the Gen Y nowadays need to see more before commenting OT = inefficient.

they are still fresh, not fully/completely exposed yet. wait till they see more fields and more things before making general statement.

etc, research team usually work round the clock, they start their work after the market closes, prepare research report by 9am next morning. they use their lunch window period to prepare update report before the market re-open by 2.30pm.

in some investment banking line, authorities come back to you at 4-5pm with a 2-3 pages queries sheet and demand clarification by the next morning. means that night you have to work like mad.

Gen Y nowadays want high salary, easy life, easy workload, no OT, sharp sharp leave everyday and any other thing that you can think of.

Put them into that shoes and I guarantee you they will resign in a month's time. Saw that to plenty of people.

Saw even one resign in day 2 cause don't know how to drive around in KL and refuse public transport (in the past daddy mama fetch).
