🤯 Tech screens in big tech

What’s a phone screen?

For those who don’t know, a technical phone screen is usually a chat with an engineer or manager to make sure you generally sound like you know what you’re talking about. If you do well on this interview, you’re onto the next round of interviews (usually the “on-site” round).

I can’t disclose the names of these companies, but I obfuscated domain-specific questions so that you can get a general idea of the questions they asked.

And yes, they’re actually offering FOUR HUNDRED FIFTY THOUSAND UNITED STATES DOLLARS for these types of positions.

Can you pass this phone screen?
