Pros
If you like to punch the clock, it's a decent place to work and comp isn't bad depending on how well you negotiate. Benefits are good. All the typical tech company things like snacks/decent hardware/ping pong etc... If you're in it for a paycheck and benefits, it's not a terrible place, and at least in my tenure there they didn't lay off or fire many folks and bonus goals were realistic and usually met. They do spend considerable effort trying to create a sense of culture and there are some genuinely good charitable causes that they contribute to. The HR department are good people for the most part and are trying to do the right things for their employees. There is a heavy mix of new and antiquated tech and disparate products due to several acquisitions, so what you do depends a lot of which team you work for, but there are some decent projects with "newer" tech to work on.
Cons
There isn't much reward for going above and beyond here. As is the case in many places, awards go to those in the clique. If you're not in the clique, you are mostly ignored more than 1 layer up. If an idea didn't come from the CTO or one of the few people he favors, it's gonna get shut down while the CTO's ill-advised pet projects that don't really benefit customers become highest priority because he's decided he likes some shiny new tech. He also has some serious anger-management issues. Once you get on his bad side, you aren't going to easily recover. Q2 will hire you no matter your ethnicity, sexual orientation, etc..., but keep in mind that when Q2 makes money, it's chairman, Hank Seale, makes a lot more money than you do. He then takes a significant amount of that money and donates it to dubious hardcore right wing causes and candidates (like donations of 500K to Trump and 180K to crackpot/racist/conspiracy theorist Louis Gohmert). Look up Lyssa and Robert Hank Seale III on any of the donation transparency sites for more information. So if you're wondering who donates to politicians that support voter suppression, bathroom bills, and random conspiracy theories...well if you work at Q2, you do indirectly. That's Hank's right of course, and personally he's a very nice person, but one reason I left was that I decided I didn't want to personally contribute to his efforts. I still remember when he got on stage at one of our town halls (entire company present) and stated [paraphrasing] that "Obama thinks he's a king and in America we don't have kings". CEO Matt Flake basically ripped the mic from his hand before he could go on any further. My jaw hit the floor and I seriously considered walking out that day. They've made a lot of ill-advised acquisitions in the last few years that increased their customer base and addressable market but also came with incredible downsides for the company and their stock reflects that. The days of making good money from Q2 stock are over. Leadership typically makes acquisition decisions in advance and then asks for diligence to support their foregone conclusion, ignoring anything that contradicts the acquisition. Finally, they've gotten pretty sue/threat happy towards exiting employees in the last few years when they seek employment elsewhere in the financial services sector. This alone is worth some thoughtful deliberation before accepting employment there.
