Aurora Innovation Software Engineer interview questions

I applied for a full-stack engineer position. I received a call from a recruiter a couple days after applying. Next, I did a technical phone screen that was fairly easy and was invited for an onsite interview in Palo Alto. The onsite consisted of 4 interviews: 2 whiteboard coding, 1 system design, and 1 domain chat with the hiring manager. The system design question seemed very reasonable. The hiring manager was friendly. The 2 whiteboard challenges were unusually difficult. I have done several whiteboard interviews before but never received questions this hard which threw me off. After the interview I went home and solved the first white board problem in ~1hr on my laptop and even with concise code, it would be hard to fit the full solution on a whiteboard. I don't feel like these 2 whiteboard interviews were a fair evaluation of my skills. Advice to interviewers: Please make the phone screen difficulty more comparable to onsite so that fewer candidates face failure and waste time at the onsite.

A recruiter contacted me over linkedin and wanted to get me in touch with the lead recruiter at Aurora. It took her one month to get that scheduled. Then the lead recruiter said he will send out an online test for me to take. Two months later I still have not received that test despite multiple reminders to both the above mentioned recruiters. I don't think I have had a worse experience in my life.
