A few years ago, I submitted a glassdoor review stating that the large teams within health catalyst didn't communicate nor collaborate very well. This has improved significantly and I have seen large steps taken to break down barriers and collaborate better. This is still an issue but I am optimistic that it will continue to improve.
Survey fatigue! I can only answer the questions "Would I recommend working at Health Catalyst to a friend?" so many times! Senior leadership does let us know they read reviews and use the results of surveys, but I have a hard time caring when most of the questions are the same and get over a dozen surveys a year. It seems they value being "Best company to work for" more than utilizing the answers and improving. It is important for recruiting, but I think if the employees are fatigued, they will give less accurate answers and just give what they think senior leadership wants.
