D-Wave Quantum interview questions

First there was a general experience phone chat with a recruiter, followed by an hour long online technical test and phone follow up. The follow up went well initially, but then they asked me to review the code that I'd submitted. However, this was not possible because it was an online test and I no longer had access to the code, and they didn't provide me with a copy. Essentially I was reviewing the code completely blind and I made some errors, so this part didn't go so well. I then received a follow up mail a few days later saying not to worry since they understood I didn't have the code, but then I received no further communications from them. I even emailed them a couple of weeks later asking if there were any updates, but they didn't respond. Usually companies give a clear 'regret' rejection mail, and I find companies that don't do this to be exceptionally unprofessional. Coupled with what I consider to be a very unfair technical follow-up, this interview was an extremely negative experience.
