Meta Software Engineer interview questions

The interview process is considered to be quite slow, weeks after the initial phone scan, I am still waiting for HR to get to back me.... The HR told me is expected to take 2-3 months to go through the entire interview process.

Recruiter emailed me to set up a phone call. Afterwards scheduled a screen interview on their careers portal. If screen interview goes well you schedule a virtual on-site interview which consist of 4-6 interviews.
