Pros
The bank tries hard to invest into their own people by providing professional training, seminars, and mentors. Unlike other top retail banks, Union Bank gives opportunities to their own qualified employee's first before anyone else. Things like community involvement, philanthropy, and volunteering is required for every employee who works of the bank. In addition, the networking atmosphere and the company's intranet is what differentiates this bank amongst the other competitors.
Cons
One drawback about Union Bank is that it doesn't formally train their employee's for any sort of certifications. Six Sigma, Financial series, and NMLS certified are the only licenses/certifications I can think that the bank offers/reimburses. Things like getting you Project Management License, technical computer licenses, or any formal training is not offered off the top of my head.
