Pros
I worked at BMO for over 7 years. BMO is willing to promote within. While it helps to know someone, it is possible to land you next move without having a connection. BMO is an advocate for hiring culturally diverse talent. Being a large financial institution, it often pays salaries above national average (especially in corporate roles). I made many friends over the years that I keep in contact with.
Cons
Despite the higher salary, you should be prepared to juggle a multitude of responsibilities. Work-life balance can be difficult at times. Retail sales positions are highly competitive and it is difficult to meet goals. There is a lot of turnover in retail. Management is often weak in both retail and corporate. My most recent direct manager had over 70 people reporting to her (this is just poor structuring). My manager prior to that was verbally abusive and unsupportive. It was really difficult to get the attention needed as a growing professional.
