About a year ago I was really interested in Health Catalyst, even to the point that I was hoping for an offer. I would most likely have accepted it. I thought that I would be a great fit for the company. I already had multiple years of experience in the healthcare industry, all of the requirements and many of the desirable requirements on the job posting, and I even was coming in as a direct referral. A current employee of Health Catalyst spoke very well of the company and submit me personally to their hiring department. I was set up to take the take-home development assignment. I worked on it for probably 6-8 hours at home after working from my current job and believed that the project worked correctly and looked good. After I passed it along to the development manager, I was told that the company wasn't interested in me. I asked for more details because I tried to follow their vague instructions as well as I could have. After pushing for a little more feedback about why I wasn't up to par, I was told that I needed to use a technology, AngularJS, that wasn't even specified at all for the job requirements or from the poorly described task assignment. This was obviously a very bad experience for me. I spent a good amount of time working on the project to only be turned down because I didn't use a specific technology. Even though my project worked correctly and did what was specified, I wasn't even offered the chance to come in to speak with the team. I don't know if it would have worked out with the company otherwise, but if I was willing to spend that amount of time to impress the company, the least they could do would be to bring me in to talk to them.
