Ask HN: Will you give me a mock interview? Front End focused, “Big Tech” style

Overview: I'm preparing to leave my first job out of college after 5 years. The goal is to become a permanent remote employ for a Big N. As this is my first stint in interviewing post-college, I feel pathetically underprepared for the gauntlet that (I've heard) Big N interviewing is.

Background: Recently promoted to Team Leader and Senior SWE; however, this is due more to my communication/people skills than deep technical knowledge. I'm full-stack, focused on the front end (and want to stay that way) - Javascript/React.

Companies I'm looking at (if this helps with context): Airbnb, Atlassian, Coinbase, Digital Ocean, Dropbox, Facebook, GitHub, LinkedIn, Netflix, Reddit, Stripe, Twitch, Twitter, Zillow
