Pros
Wells Fargo is a large company that one could move up and/ or around in if (s)he seeks a career in the financial services industry and is very sales-oriented. The benefits given to employees are very good such as your insurance, retirement, and a myriad of other financial perks you get by working at a bank. It is also a company that values diversity and tries to reach out to minority demographic groups--especially the growing Latino population in the United States. If you know Spanish or any another language this company is likely to value your language skills and cross-cultural competency.
Cons
Wells Fargo is a great opportunity for you if--and I mean IF--you are a very sales-oriented person. For example, as a teller your job is not simply to provide efficient, accurate and courteous service to the bank's accountholders as one might think. As a teller you are NOT simply working in customer service. You ARE working in an entry-level sales position. You have a sales quota to meet every quarter and if you consistently do not meet your quota you will no longer be employed by Wells Fargo. It is as simple as that. If your personality is not geared toward trying to convince a customer who merely wanted to come in and quickly cash their check why they should get a credit card, open another account, or use some other financial service, then this job is clearly not meant for you. Be able to suceed at giving a rapid-fire sales pitch or you will not make it.
