I had a phone interview and an on-site interview that were very technical.

They were difficult but reasonable, and everyone was extremely friendly, probably one of the most pleasant interviewing experiences I've had. I was ready to join, and even mentioned I could handle a pay cut.

Once I passed the interviewing phase, they told me they were interested in hiring me but would not tell me my starting salary or options until I decided to join. This made me feel uneasy, so I dragged out my decision. Then the founder called me and told me that because I took 3 days to think this over, he doesn't trust my judgment, that I have a "millennial attitude," and does not want to continue the process. I formally declined after the conversation.

After my interviews, I was 100% decided on Wealthfront; I even turned down my other offer and canceled an interview. But the fact that they were not transparent enough to give me an honest offer made me very uncomfortable. I still think they're a good company with a fantastic product. I invest with them and I follow their blog. But, as their blog suggested, I was looking for a company that values transparency and will give me a fair offer.

The CTO asked me a question that involved Java 1.8. I haven't worked with that version at all.

It was fun to actually learn something new during an interview. Overall, all of their questions were difficult but very fair. The interviewers were helpful, and it felt like a collaborative environment.
