Pre-interview screening video call (approx. 20-30 mins) with head of engineering asking questions aimed at elaborating aspects of CV. Also included some technical questions e.g. what are the P, I and D components of PID Control, what does the stability of a signal/response (i.e., decaying with time) mean.
If the pre-interview call goes well, you will be invited to an in-person interview (approx. 1 hour), however no reimbursement of travel expenses will be provided. During the interview, I was asked a mix of competency questions along with technical questions.
