Pros
Competitive benefits. Job training and continuing ed are above average. In general, product offerings are popular with clients and agents, which leads to fewer complaints/problems with existing customers, and helps agents sell the products effectively. ING is generally still a sound company despite the "downturn" that we're all sick of hearing about.
Cons
Below-market compensation in non-management positions. Bureaucracy is out of control. Internal hiring between business units is difficult to impossible, at least in the US Wealth Management division. IT and systems are generally 5-10 years behind, with seemingly no priority to improve on the part of management. Many processing functions have been "offshored" with no cost/benefit analysis.
