Technical Behavioral

I got a message from a recruiter on LinkedIn. They told me to apply online first, and then they set up a 30-minute video call. After that, there was a 1-hour technical round with a senior data scientist and the Hiring Manager. The final interview was supposed to be with the team. I haven't heard back since the technical screen, even after following up twice with the recruiter, and eventually got a generic reply saying I wasn't moving forward.

The first round is an HR screen where you talk about why you want to be a data scientist. If that goes well, they'll schedule you for an interview with the hiring manager. The hiring manager will ask questions about your resume, so make sure to prepare for that.

Behavioral Technical Coding Presentation

It was a really great interview process. The first thing was a chat with HR. Then, the very next day, I had an individual interview with the VP of analytics. After that, I did a technical presentation about my work experience for the entire team, and there was also a coding challenge. The final round involved presenting my solution to the coding problem and answering questions about it. The entire process wrapped up in about two and a half weeks, and they extended an offer. Everyone I met made me feel super comfortable.
