To be clear, overall I still think Intuit is a good place to work. Company values are good, WLB is reasonable, and they clearly care for their people. With that said I will be transparent about the most frustrating aspects of Intuit I have seen: the product, the operations, and the talent.
I work on one of the larger products aimed at accountants within the org. The degree to which our customers hate the product is really disturbing- it's just that they feel they have no viable alternative in the market. As a person who loves the craft of product, it's demoralizing to work on a product that people generally hate using. Leadership and the company seem to show minimal interest in making the product better or more lovable. In fact, I've seen and heard of major product changes that went into beta or a/b testing, were failures by all metrics measured, and shipped anyway.
Operationally, Intuit can be quite frustrating. Even if you are lucky enough to work on a fast moving team, release approval and deployment cycles are so slow there really is no such thing as a fast turn around. If you have to work cross functionally with another team, I've found many teams to be a bit territorial. Many people I interact with are under the impression they and their job exist to maintain existing systems/the status quo, not to deliver new value to the business (much less to the customers). The 3 days required in-office is also strange given there aren't really assigned seats and you may not work locally with anyone on your team- it makes this rule seem very arbitrary. I often go into the office and am at a desk on Zoom all day (there is a meeting room shortage)
Lastly, the overall quality of talent seems lower than I've seen elsewhere. When you have tens of thousands of employees, I'm sure maintaining quality can be a challenge. I have worked with principal level product people who have trouble with basic communication, little attention to detail or follow through on direction, and are unable to advise on basic product behaviors or solutions. To be clear, I've also worked with very talented people at Intuit, but it seems like an unusually even mix.
