Meta Internal Solutions Engineer interview questions

Recruiter contacted me and asked if i was interested. Phone call with a recruiter. Next was a 30 minute online coding problem, then a 30 minute phonecall with the hiring manager going over my background. Next an onsite with 2 x 45 minute whiteboarding coding sessions. Then a 45 minute behavioral and a 45 minute system design. Final round was a 45 minute videocall coding interview. Total process took about 3 weeks.
