Pros
The obvious pro of Medallia is the culture and especially the people. Medallians are compassionate, super intelligent, hard working, fun, adventurous, and just...wonderful! My coworkers have become of my of best friends. I left a job in entertainment because I was so inspired and excited by the people I met during my interview process...total career 180, but it's been 100000% worth it. But beyond the people, to be part of a company at this stage (mid-size, still private, growing like crazy) is an absolutely amazing growth opportunity. Sometimes I feel like I'm getting paid to go to business school, because I'm witnessing firsthand a) what it's like to take a company from 300 to now over 575 employees, b) how we're bringing on new, huge clients, and c) how to maintain culture while scaling.
Cons
As is the nature of a growing company, there are certainly fewer standard practices and procedures in place. But honestly...I would so rather work at a company where we're all figuring things out together as we go, and constantly learning, rather than just filling in a spot/slot/role etc left by someone before me and going through motions.
