The interview process was quick. I spoke with the recruiter and we decided to move forward.

Next, I had a video call with one of the engineers on the team. He asked about my prior work experience, tools used, and working methodology, followed by a coding question on graphs.

I was invited onsite after the phone screen. The onsite interview comprised of four rounds:

• Three rounds involved coding and design questions.
• The last round was with the VP of engineering, who asked questions about my past projects and employers. There were no technical questions in this round.
