Contacted by a recruiter through LinkedIn, they set up a code pair round for the tech screen. They restrict the languages in which you can take it.

The recruiter was nice and gave sufficient info on salary, etc.

After the tech screen, I got ghosted. I can't stand companies that ghost. Blacklisted forever.

Got the discounts-customers question mentioned by other posters. The question itself was not hard, but the interviewer was condescending, non-communicative, and judgy.

I let them know ahead of time that I'm coding in a language that I haven't used in several years, so they were understanding of my syntactic limitations, but the snobby attitude along with poor lighting on their end made the atmosphere feel not-so-professional.

As if this weren't bad enough, the interviewer actively led me down wrong paths at least twice (and I had to correct them, and explain why). I don't mean that they asked me about alternate approaches and why they were not valid. The interviewer actually suggested my solution was wrong and will not work for certain cases, and I had to take a few minutes to help them understand the code even though I had already walked them through my approach before coding.

Imo the interviewer was not well-trained and the shadower was silent throughout.
