first a phone interview, then I got invited to onsite. Skills test is quite simple. Then four 1:1 interviews, they talked about the projects they've been working on to see if you're a good fit for the team. Just like other reviews said, be sure to elaborate on your quantitative research experience. As for the company, the employees seem nice and really smart. The whole onsite process took 4.5 hours. It's quite exhausting, so come prepared.

I was initially contacted to analyze a set of data concerning patients grouped in various manners (age, payment method, stay of visit, out patient, etc.) I only had to analyze one sheet worth and information and provide only a single page write up. After this, I had a phone interview with rather basic questions to get to know me, go over my resume, and see if I was interested for the job. We didn't speak about the excel analysis as that was only for the in person interview. Afterward, I received an email stating they didn't want to move forward without an explanation.
