I have been using Marketo now for 3 years, have my MCE, and I still don't feel like I know all the in's and out's of Marketo. I work for a somewhat small company (around 50 employees), am the only Marketo Admin for my company. We previously used Pardot before switching to Marketo and we use NetSuite as our CRM. Our onboarding was rushed due to having a deadline on when our Pardot contract ended so I had about 4 months to figure out how to implement the transition between systems as well as learn the basics of Marketo. The only training I had was the 20 hours or so of Marketo onboarding help. I also do not have an IT background and had limited access to an IT expert during our Marketo implementation and integration with NetSuite.
When I read Community posts and see Marketo webinars by people who obviously have an advanced grasp on Marketo, I wonder how long it will take before I get to that same level of expertise. I'm curious to see if my situation is unique, or if there are a lot of other Marketo users out there like me!
