Stop and start with unresponsive and unhelpful recruiter. If I was told I'd hear about next steps within a week then I wouldn't hear back for 3 weeks. If I checked in to respectfully ask for an update there was usually no response at all. The position ended up being pulled and they "paused" hiring though I don't expect it to pick back up. It may be due to a re-org, or maybe not - who knows, but I didn't find out for weeks and only after reaching out to ask about an update. This was among the least respectful interview experiences I've had in my career - the power dynamic is firmly on the side of the Reddit recruiter. The few times they sent emails they were informal to the point of being unprofessional - unformatted, riddled with typos and grammatical errors - like they were sent in a rush as though it was a text message to a bestie. In a way that would be fine, but if I had done the same thing it would have been grounds for cutting me from the candidate pool. Reciprocal respect in communication would be nice even though the current labor market means they technically don't have to treat their candidates well. This reflects poorly on their org.
If you engage with them, go in expecting the absolute bare minimum in terms of how you're treated throughout the process. Hopefully you'll be surprised to the upside, but I know one other person who had the same experience for a different position, so best of luck.
Short version: pretty gross for an org that pays a lot of lip service to building community.
