New generation of HK IT staff -lack of mentors?

Recently there are opportunities to work with IT staff from Big B and SC bank.

Big B guys are nice but do things without any queries while in doubt and cause me some troubles and annoyance. They are recently lack of staff and sending all their 'Stretch-Wing' trainees to do lesser critical jobs. I have no complains for these SW but their seniors could have given them clearer guidelines.

SC bank people are more confident but in certain situations I have to let them know that they have some wrong diagnosis that I have observed and suggested alternative ways to troubleshoot again.

Both cases point to one common thing - a mentor with experience can make a great difference in front line job.
