Technical Coding Presentation Behavioral
The interview process kicked off with a recruiter phone screen, followed by a second phone screen with two Data Scientists that included some straightforward live-coding on a shared screen. Then, there was a homework assignment, and finally, an on-site interview. The on-site was pretty standard for a non-Junior DS role. I was given a 'homework assignment' ahead of time, and I presented my solution to the entire DS team. They asked about my methodology and quizzed me on potential next steps. The 1:1 interviews were the typical mix: algorithmic whiteboarding in Python, discussions about Machine Learning projects, whiteboard probability problems, and conversations with some of the DS's about their projects and how I'd approach them.

Technical Coding Presentation
It was a three stage interview process. First, there was an on-site technical interview that lasted about 30-45 minutes. Second, I had to complete a data analysis assignment and report, and I was given a week to finish it. Third, there was a long on-site interview. It began with discussing my data analysis assignment results and report with the entire team, followed by several one-on-one meetings with different team members.

Technical Coding Other Group
It was a personal interview, then a data analysis project, and finally a group interview. The technical interview part was great. However, later on, some SVPs and employees had a pretty interesting attitude that felt a bit demeaning. While I appreciated the technical interview itself, their attitude wasn't something I was looking forward to.
