I initially applied for full software engineering (SWE) out of college. After a phone interview and an online coding sample, I was flown onsite (in Seattle, per my request) for four one-hour whiteboard interviews. They let me code in a basic text editor, which was nice, although I ended up mostly sketching out algorithm ideas on the board for two-thirds of my time.

A few weeks later, they told me I wasn't quite ready for full SWE, but that they wanted to consider me for the engineering residency program. This program is designed to provide additional training and, if I performed well, transition me into full-time within a year.

After two more phone screens, I received an offer.

Everything everyone else has said, basically.

They are somewhat more creative than other questions I've gotten, but they really do just rely on the basics:

• Data structures
• Algorithms
• Runtime analysis
• Class design
• Concurrency & scalability

Etc. You just have to know the heck out of the basics.
