Pros
Humana is a good company, if you are able to find yourself in right team. On plus side - It looks good on your resume and they have 1.25% contribution to 401k (only after you work for 2 yrs). Typical big company with disconnected departments and its horrible to make even small thing happen.
Kontras
Humana is divided into number of disconnected teams and each team has there own rules and regulations. IT Managers will make or break a rule based on there convenience and openly favors favoritism. Humana encourage you to report such things to there ethics helpline, but it is just a joke. Overall my experience was not good with humana. Culture at humana was so toxic that I finally decided to say good bye. For big company like humana, you can get lost easily and that is reason it is important to choose your first boss carefully to have career success.
