Wander (CA) interview questions

First, I got a 30 Minute phone interview. Where I was asked about my educational background and my past experience as an RF engineer. I heard back in a couple of days and another phone interview was arranged for a week later. During the second interview, I was introduced to the technology Wander is working on and was asked more questions about my RF engineering experience. I heard back again in a couple of days and arranged for an in person interview a week after. In the interview, we discussed the role further, what is expected out of the RF engineer and how does my experience and education line up with it.
