Chartmetric interview questions

Had a short informational interview. I was then given a fairly large case study - they gave two prompts and said to complete one of them. They said and said it would take 6-10 hours but I spent closer to 25 to complete both. After they reviewed the case study, there was another interview with the CFO. The final round was in person where we reviewed the case study further, and also spent a lot of time having general conversational to see the culture & character fit.

Technical questions with the information I wrote in my portfolio and resume. I applied for a web engineer position. I answered which skill I used in my project and I was asked React, and SQL questions.
