Locus Robotics interview questions

Have applied via the recruitment system on the website. Received a confirmation. While waiting for a response on my application there was no communication or update. Locus Robotics didn't share a name of a contact person or phone number so you can't call them. Neither can you find a phone number online and the US number is for sales only. I've send an e-mail for feedback, but didn't receive an answer. 2 Months after the application I received an automatic e-mail that they didn't choose me. I respect their decision, but not the lack of communication, no replies and 2 months waiting. Now they spam me with e-mails of workshops and other offers. Although I unsubscribed, they keep sending.

I set up a time with the recruiter for a first phone interview and they never called. I emailed to confirm I had the time correct and they never responded. A week later I followed up again and they never responded.
