TLDR: Marketing expects long hours, has awful management, rampant nepotism, resulting in constant turnover both willing and forced.
Work/life balance is terrible, weekend/evening event work is mandatory and responsiveness to evening/weekend emails is a requirement. Employees who do not work long hours, "volunteer" for events and respond to emails/TEXTS after hours are considered to not be hard workers and looked down on. Culture breeds unhealthy expectations starting from the top and trickling down.
Nepotism is a real problem at Canvas. From the top down, leadership most highly values who you know and who you're related to rather than your work. The marketing team is especially bad about this. There's a reason why virtually the entire team has turned over, despite being very highly skilled and previously happy in their workplace.
Management does not know how to treat people, and if you file complaints then you are quickly labeled as "not a culture fit" and doomed. Said culture is at its core unhealthy and often inappropriate. You will be handed work you've never done before without any training and reprimanded for not doing good enough or working hard enough. If you're working on a large project, no matter how fast you work you will not be working hard or fast enough and, again, will be reprimanded.
Avoid the marketing department at all costs. The interview and first few weeks will be smoke and mirrors, but after pulling back the curtain you will be looking for a new job within a year.
