A little bit of overkill. You have an initial conversation with an HR rep to see if you can hold a conversation. Following that, we had a technical phone interview about SQL basics (nothing hard at all). Finally you have an in-person interview about how you are as a person, learning, work ethic, etc. After that you go directly to a technical interview with two directors. Easy interview that doesn't really assess the knowledge you have.

I submitted my resume and cover letter on the Health Catalyst website. The next day, I got an email from the recruiter wanting to set up a phone interview. The phone interview with the recruiter lasted about 20 minutes. A couple of days after that I had a phone interview with a technical director where he tested my knowledge of database design and the SELECT statement. The same day, in a timed SurveyMonkey survey, I had to write three queries on fictitious employee data. A few days later, I had a final in-person interview where I had to walk two technical directors through a business problem and write a query on it. Then I went to lunch with two other technical directors and they asked me about my work experience.
