Slack Engineering Manager interview questions

I didn't even get to the interview stage. Had a warm intro to a recruiter. After some initial back and forth emailing, the recruiter went off the radar for 2+ weeks. By this time, I already had one offer and was expecting a second one soon. I let the recruiter know I was still interested in Slack. Another 1+ week goes by before I get a response, asking if I had taken an offer or was still looking. I had already taken an offer at this point. Honestly, if this is how their team deals with WARM introductions, I can't even imagine how they treat candidates who come in through their normal pipeline. Looking at some of the other interview reviews on here, it's very clear that this is a recurring problem, not a one-off one. Even if I hadn't taken an offer, I wouldn't have pursued Slack any further.
