The phone interview with the recruiter was about a week after I applied to the NERD program. It was a couple of simple STAR questions, as well as the four fundamentals of OOP and their descriptions. During the technical interview, which is typically a week or two after the phone interview, I was asked a few simple STAR questions again, asked a couple questions related to software engineering principles, asked about my personal projects, asked if I was familiar with certain concepts in Java/C#, and asked to do a very simple coding exercise which required familiarity with common data structures and array/string access and manipulation (Leetcode Easy). All of the questions (with the exception of the coding exercise) were phrased in such a way that they were just asking me if I'm familiar with a certain concept, not grilling me for an answer. Schwab gets back to candidates with an offer very quickly.
