Opendoor interview questions

The process starts with a phone screen, which is easy enough as long as you've done some basic research on the company. The next step is a technical screen with another engineer, who will ask you to solve their favorite programming problem. As others have noted, getting to the correct solution doesn't mean you will pass. Their standards seem arbitrary to say the least; it's not clear what they're looking for. On the positive side, all involved were timely and polite.
