I applied through a recruiter. The process took 3 weeks.

The interview process had four rounds that happened over the course of about 3 weeks. It started off with a conversation with the hiring manager to talk about the job, some technical questions, and a brief discussion of my resume. The next step was a 1.5-hour coding screening. After that was a technical interview going over the experience on my resume. The last was the onsite, which had four other interviews:

• Presentation of a topic of my choice
• Values
• Teamwork
• Technical interview on general state estimation topics
