Pros
The biggest pro for Cvent is the corporate culture. It is a very young office so it's practically impossible not to make friends which makes the workplace very enjoyable. Cvent also places an enormous amount of responsibility on you from the get-go which gives you a sense of pride when working. This also leads to quick growth (in both title and salary) and opportunities. Even though I've only worked at the company for under 2 years, I already manage my own clients, manage my own schedule, and traveled to Cvent's India office to train Indian colleagues for a full 6 weeks (all expenses paid). Additionally, I travel to client's offices as well for onsite trainings but it's not an overbearing amount. All-in-all I've thoroughly enjoyed my time here and the culture makes this place a great first job and transition from the college experience.
Cons
The company is very young (many just out of college) so working with all young people can lead to a loud and relaxed workplace (may not be for everyone). The hours are also on the longer side as the company is growing very quickly so there is a ton of work to be done. You must be a flexible and easily adaptable person because there is a lot of learning and thinking on the fly (again due to the rapid growth).
