Working in an ECM group?

I had wanted to work in markets since my sophomore year and initially focused on recruiting for roles in S&T and capital markets. After my interviews, I was offered a role on an Equity Capital Markets desk with a team I clicked well with at a prior firm networking event. 
 

Before starting my internship this summer, I want to ask ECM folk what your honest thoughts are from working on the desk either as an intern or as full time. Did you enjoy the work? Were there any surprises or challenges to the role?

Those who left for other jobs, what led you to that move? Thank you.
