Pros
Wells Fargo as a whole is a great company with good employee benefits. Career longevity is very possible as WF has been around for many years and is very profitable. It is prorbably one of the most stable and reputable banks in the U.S. Good chance of fast advancement if you are good at sales. Also, there is alot of lateral mobility within the company since Wells Fargo has so many different divisions.
Cons
Working as a credit manager for WFF is a sales job. As w/ any sales job, the pressure is high to hit quotas. Sometimes, the job is monotonous. The mornings are spent making outbound sales calls to current customers; the afternoons are spent meeting with customers. The products sold are not very competive with other banks, so if the customer is smart enough to shop around, they will usually find a better deal elsewhere which is frustrating when you are trying to convice people that they NEED your products. There is a very high turnover rate due to the pressure, monotony, and the lack of competition w/ local banks. The base pay is not quite bottom of the barrel, but almost. There is now a nice bonus piece based on sells, but only if you sell a fairly substantial volume. The manager pay is obviously much higher and the bonuses are much higher, but that is 3 promotions from the credit manager position.
