Pros
I've been with TriNet for about 5 years now and this is a great place to build your career. I came on with little experience and was met with great coaching, dedicated mentors and a strong team culture. Folks here genuinely want to help you succeed. Needless to say, you have to be a self-starter. Nothing is handed to you, but we do a great job of team-selling and group coaching. Another reviewer mentioned a toxic environment with shark tank bullying sessions. That couldn't be further from the truth. Shark tanks (role plays) are done by mentors, leaders, peers etc. with the sole purpose of helping each individual overcome their fears/weaknesses in public speaking and running a confident meeting. Those shark tank sessions were absolutely vital to my success and prepared me for the toughest of meetings. I wouldn't trade that experience in for anything and I think anyone who would take issue with those sessions is not taking his/her personal and professional growth seriously. And for what it's worth, I've never heard a group of people celebrating or making fun of someone who had a rough meeting. Not once in 5 years.
Cons
Any company that is growing to the size that we are will have growing pains. That's to be expected. I'm of the belief that giving feedback and trying to fix things is the winners' mentality - not complaining. My experience has been that YOY, we are only getting better and more efficient - especially around how we service our 17k clients. Sure, I get frustrated from time to time, but when given the feedback, our team leaders improve case over case.
