There's a lot to say, and I might expand this review later. This company tries really hard to get employees to buy into how great they are, and to adopt cvent as part of their personal identity, and that should be a pretty big red flag right there. Higher-ups, and individual employees, often sprout rhetoric about, "how great cvent is," but I suspect that anyone who's using that rhetoric and isn't in management is doing so because they were snatched up right out of college and don't know any better.
One of the first warnings was that about a month or so after I started working, I received a box with the obligatory company swag (branded notebook, branded coffee mug, branded stress ball, branded mouse pad, I think there was also a pen) and a letter explicitly instructing me to post on LinkedIn and social networks a picture of our swag and a message about how excited we were to work for cvent.
Two or three months after starting, I was told very directly that as a senior engineer I was expected to work, in general, over 40 hours a week (it's not uncommon for software engineer in a salaried role to sometimes go over in order to get a project out the door, or solve something that came up unexpectedly, but this isn't a weekly expectation). This company is trying to create the atmosphere of really Google and early Amazon where employees are so ridiculously ecstatic to be working for them, that they'll gladly sacrifice their personal mental and emotional health.
A lot of other employees write on here about being locked into some kind of ridiculous contract where if they leave the company and under two years they're expected to spend several thousand dollars to "pay back" the company for their training. Thankfully, I was not subjected to this.
I took off after a little more than a year, and then took a few months to work on my mental health before looking for a new position. This time, I was a lot more particular about who I interviewed with, instead of just letting some random company aggressively recruit me on the basis of being so excited to have me and offering me a salary bump and a senior title.
This is my first comment and hopefully only negative review I have left for former employer on Glassdoor.
