It was a pretty easy interview, as expected for just an internship position. First, I had a phone call with the recruiter where we had a light conversation about my background and experience. Then, there was an onsite technical interview, which I solved using a whiteboard and marker.

The interview process involved several stages: first, a 30-minute recruiter chat. Then, a 2-hour coding test with three problems. After that, a 45-minute technical interview with the hiring manager and another 1-hour technical interview with a data engineer, which included coding. The final stage was an onsite interview consisting of four sessions, three of which involved coding. I was expecting the onsite schedule beforehand, but it wasn't provided as promised by the recruiter. During the technical interview with the hiring manager, he was very interested in my AWS experience. I mentioned I only had basic exposure. This came up again during the onsite, and I reiterated my limited experience. It felt like if AWS was such a big deal, the interview could have ended earlier. The onsite also had a lot of uncomfortable, unprofessional NDA-type questions, which was strange for a software engineer role that didn't seem to require very specific experience. It seems the role actually needs experience in various areas, judging by the interview stages. Overall, it was a very unprofessional and time-consuming interview experience.

Technical Coding System Design Behavioral
I was first contacted by the in-house recruiter and had a quick phone chat with her. Then, I had a take home exam to complete within 2.5 hours. After they reviewed my exam, I had a video call with the Data Architect, Team Lead, and VP of Product. Following that, I was flown to Santa Barbara for an onsite interview where I met with several people in person and some remotely via video. I also had lunch with the Santa Barbara team. The final step was another video call with the Team Lead where I was asked for recommendations. Evidation Health was very accommodating to my needs during the interview process, making it one of the best I've experienced.
