Column Software Engineer interview questions

I applied at Column in April 2022, they were pretty reactive and I passed 4 interviews (screening, pair programming, CTO, software engineering manager) on 3 weeks. They conducted the interviews in one of the best ways I’ve been into and I particularly liked their transparency. After my last interview, I never heard back from them again. As I needed to make a choice quickly I sent a follow up mail but they didn’t bother to answer either. From the previous posts it seems to be pretty common for them, I’m a bit disappointed as it gives performative vibes to some positives points, had I known earlier I wouldn’t have waste my time applying to their offer.
