Vantaggi
RIP due to Doge:/ before then it was Russian roulette to whether you had a chill or sucky manager, You usually worked with several, hopefully you got at least one chill one and one interesting project where you're not a paper pusher. Think of all the awful things about consulting, and then turn it down a notch. Resonance, pre-doge, wasn't nearly as bad as some of the larger consultant firms, less stable, though, too, and didn't match the stress with a higher paycheck
Svantaggi
As stated in other reviews, pay was bad, especially for the industry; the company was bad at promoting internally, turnover was high, especially if you were not mid to upper-level management. The culture gave lip service to work life balance and then expected you, but if you got lucky, you got on a good project with a talented and caring manager, then life was great, but you don't really get to control that
Because of the nature of the job, most all the salaries were open info, and there was some sr analyst that analyzed all that data and found that men got paid higher than women even for the same job title, Men were also found to be promoted faster and more likely to be in leadership, despite the majority of the company being female.
