The reviews of said company on Glassdoor and Blind all have a common theme that the company hires great people, but the executives and leadership in general are just not good at all. The reviews range from "all in all its pretty good, management could use some work though" to "the company and product are going to implode this is so bad" so I'm not sure how bad it is there.
I think it's impossible to know how true this until you work there, but I'm wondering how much stock I should put in these reviews and if I should just disengage from the interview process because of it or not.
Look for a bunch of positive reviews that sound straight from corporate. This means the company paid for those (red flag).
Look for a trend in negative reviews that goes beyond the 'I hate my boss' reviews.
My personal experience with smaller companies I worked for is that they are accurate.
Like if someone says none of the execs know what they're doing, it's going to fall apart any day, are they a new grad, someone who's only worked at big companies with everything formalized and an established business, or are they startup veterans. You don't really get that context.
So the best you can do is try to judge it based on your experience. If you find those comments concerning, maybe it's not a good place for you. If you think "yeah everyone says that" then maybe it's ok.
Generally 3.5-4 is workable. 4-4.5 is dream job. 4.5 and higher is very rare, probably has unlimited paid time off, dental, servant leadership, team vacations on work days.
3 and below tends to be at the brink of imploding.. senior leadership is probably job hunting, illegal stuff is going on, etc.
