I applied through an employee referral.

I received a call from HR unexpectedly, where they reviewed my resume and forwarded it to the hiring manager.

I was then called for an onsite interview the following week.

During the onsite, five people interviewed me, with each session lasting approximately 30-45 minutes.

I am currently waiting on the next step.
