I'm a rising UG senior and had a final round last year at an MBB (for their internship). I got an email from the recruiter to schedule a time for a coffee chat with consultants. I signed up for a specific time slot with an unnamed consultant (just showed their initials on the time slot). Note that the recruiter email specifically said to only sign up if this office was my first choice (it is) and I know other people that interviewed last year who did not get an invite, so it was a relatively exclusive event (I remember there being ~10 time slots). Anyways, I ended up completely forgetting about the chat until that weekend, so it was too late to send an apology email.
I know that this was a stupid (and completely avoidable) mistake, but now I have two options.
A.) I just hope that I get the interview anyways. This office is my top preference due to culture fit, and considering I amde it to the final round last year and was invited to an exclusive event means that without this mistake I would have almost definitely gotten an interview.
B.) I preference a different office. I would probably get an interview at another office as I'm from a national target and got multiple MBB interviews last year. However, I would like to avoid doing this if I'm not likely blacklisted from the original office.
For formalized coffee chat events, do consultants give feedback to the recruiter (ex. He didn't show up), or is this just an informal event that the recruiter won't hear about? If the recruiter does hear about this, will I be automatically blacklisted?
