As Reddit say on their web site, they're home to "authentic human connection". Unfortunately, it's pretty much the opposite to what I saw during the interview process.
It all started with a recruiter contacting me and scheduling a quick screening call. That went fine, so a technical screen got arranged. The interviewer didn't seem to be very interested or engaged, but it's pretty common so I won't complain about it. It was a coding exercise, for which the common wisdom tells "explain your thought process in detail, don't jump to coding straight away, ask questions". When I tried to do exactly that, the guy told me, basically, to keep quiet, write my code and notify him when I'm done. That, combined with overall unfriendliness and some amount of multi-tasking from his side, created a rather bad impression.
It all went down from there. At some stage, the recruiter told me that due to some internal issue, they had never got feedback for my interview. However, in the meantime, they hired another guy for the position. So, it seems like I didn't fail the screening, but got abandoned nevertheless.
Overall, my experience is probably an outlier and I'm sure Reddit is a much nicer place as it appeared to me.
