Behavioral
The first question they asked me was why I wanted to join the company. Before the interview, they had sent over some materials about the company, which I looked over carefully. I talked about my interest in the product and how it connects to my previous work. Then, they asked if that was the only reason I was applying for the job. I was upfront and said that I was recently laid off, which is also why I am looking for a new job right now. The way they asked and followed up felt sudden and kind of discouraging. While I think being honest is important, this made me wonder about the interview's tone and if the company would be supportive of people when they are going through tough times.

Technical Coding System Design Behavioral
So, it started with like, one initial screening plus a take home assignment. Then I had two technical interviews, and two behavioral interviews. The technicals were about system design and data structures and algorithms. The behaviorals were about my resume and experiences. The take home was contributing to a big codebase in Java.

Behavioral Technical Coding System Design
Overall, Wealthfront is a fantastic engineering company and their interview process is very direct and transparent. There are several stages. First, a phone screen with a talent recruiter/HR person to talk about some past experience, with some quick Java syntax questions. Second, a technical coding interview with one of the engineers (about an hour). Third, a final round interview with two technical interviews and one engineering practices interview (design, and prior experience with testing/code review). All of these interviews usually happen remotely. Fourth and finally: if you pass the final round, they'll fly you out to visit the company onsite. Not sure if this part is technical. Overall, they have some really cool technology and were very honest and direct throughout the entire interview process. Pretty much a Java-shop, if that makes any difference.
