Phone screen with recruiter. Scheduled interview with 2 managers for the next week.

Interview with 2 managers: basic discussion with some personal and conceptual questions.

2 days later, received an email stating I was to virtually share a presentation on my highest technical achievement with the managers and senior engineers on the team. This was scheduled for 4 days later. I also had to fill out documentation about 5 other engineering projects I managed.

Usually, this interview is conducted in person; however, I interviewed at the height of the COVID-19 quarantine, so everything was held over the phone/internet.

Presentation followed by 3 rounds of phone interviews with 2 teammates on each call.

2 days later, a call from the recruiter let me know I had made it to the final interview. A scheduled phone interview with the director was set for that evening.

Recruiter called 1 hour after the phone interview with the director concluded, extending an offer.
