6sense Data Scientist interview questions

I had a fairly unique interview experience at 6sense. I actually found out about 6sense through a friend who was leaving to go to a new opportunity. My friend left on good terms and referred me on their way out. I was put in touch with a member of the data science team, and we had a casual chat about the role before submitting my resume. They provided a standard take-home challenge with 48 hours to complete. I decided to start on Friday afternoon not thinking about what I'd do if/when I had questions about the assignment (the whole team is super responsive and would have answered any questions I asked over the weekend, I just didn't think to). There were a few things I was confused about in the assignment and I ended up filtering the data quite a bit and ultimately got pretty odd results. After submitting the results for the take-home, I got an email saying I wouldn't be moving forward in the application process. I was bummed but wasn't too surprised; I realized I did some weird stuff in the take-home. I reached out to the person I was referred to and asked about where I was lacking (they said the take-home, unsurprisingly). We went back and forth with maybe a dozen emails where I explained my reasoning. After that, they took a closer look at my code and decided to invite me for an on-site! (Note that this is the only time I've ever heard of a company changing their mind about a candidate from a 'no' to a 'yes' based on a discussion with that candidate and I think it speaks to the level of openness, understanding, and, most fundamentally, the curiosity that I've come to expect here). The onsite was a standard super-day. They gave a challenge similar to the take-home on which I gave a presentation to the DS team (the CTO even came and was highly engaged throughout). I also met and had lunch with members of the data science and data analyst teams, coffee with the data analytics manager, whiteboarded sql, etc.
