Pros
This place will be a great way to start your sales career as an Account Executive. It's an extremely well established brand in the email security market and growing with multiple products that expanded their portfolio. You have a solid alignment in the partner market if you know those representatives or are willing to hone in on that part of your sales strategy. You also have many tech alliance partners (SentinelOne, Arctic Wolf, CrowdStrike, Netskope, Okta, and so many more) to help you both prospect into and close deals. The management is helpful but as the years go on, they definitely will and need to improve over time.
Cons
Your territory is definitely a factor to your level of success at Mimecast. Big brand name in major markets but not that large in others. Taking that into account, you need to be aware that things don't change for the better often in Sales at Mimecast. Changes to your territory/plan might even happen 2 months into the new fiscal year. Making it extremely difficult to align with your teams internally on how to go to market correctly. Hoping this changes but it will be frustrating if this happens for a 3rd year in a row.
