Unscrupulous practices when it comes to assessing fees and daily interactions with the customers. I often left work feeling bothered and depleted by this. Example: A high level manager made employees in one department assess higher interest rates on specific types of loans which negatively impacted the customers, but resulted in higher fees for the company. This practice was eventually corrected after legal got involved, but who knows if the effected accounts were reversed.
Biased management in all departments who promote and support the people they like (and in some cases are related to) rather than those with the necessary skills and qualifications.
Culture of toxicity where throwing colleagues under the bus and putting up with a sub-par management/team leads is part of your daily routine.
HR department is a joke. Lots of infighting and a complete lack of organization. Expect zero confidentiality when you bring issues to them.
