Regardless of what your role is, programmer, number cuncher, project manager, secretary, tech, etc… there are other employment sectors out there other than finance. If you are let go, why ONLY apply for jobs at other banks? Branch out. Try the same job role but instead of the banking sector, try the medical sector, legal, transportation, etc…. they are all hiring to you know. A tech person at Citi, can be a tech person at Koch or Walmart or Kellogs. A number cruncher at Citi, can also be a number cruncher at a hospital, or anywhere else that needs one.
Why limit yourself?
