JPM IB Superday - When Should I Expect to Hear Back?

I just had an IB superday for a 2022 SA position with JPM about 6 days ago and haven't heard back yet. The interview was specifically for M&A and the group is small but looking to grow (They have ~10 people now and are looking to hire 3 summer interns). In my Zoom room, there were only 2 other people interviewing, although there was another time slot so I'm assuming around 6 actually interviewed. I thought it went really well - I nailed the technical round and I also felt I got along great with the interviewers in the fit/behavioral rooms. The last guy told me to "keep in touch" and that he'd love to meet up in person sometime, which I thought was a good sign.

Based on how well I thought it went, I honestly expected to hear back within a few days, but I've heard nothing. HR told us before the interviews started that it would take about 2 weeks to hear back, but they told my friend the same thing when he interviewed at a different location and he heard back 2 days later. They also told us we could ask to get a response earlier if wanted. Do you think my chances of getting an offer are low at this point? Would it be a good idea to send HR an email indicating further interest or even ask to get a decision sooner? Would appreciate any advice/insight :)
