So... I got crushed in an interview. How to proceed?
So... had an interview last Friday and got pretty crushed. Built no rapport with interviewer and stumbled through technicals. For the first or second question, the interviewer stepped in 3-5 times to help/guide me... ended up making it through without him/her directly giving answer. Another question had pretty hard mental math that I got stuck up on, but nailed the overarching idea. Other questions went alright. But I literally spent like 10-15min on 2-3 questions - meaning, I'm confident there were multiple questions that they didn't even have time to ask (which I later confirmed).
So.... probably won't get next round. But the question is: I networked pretty aggressively at the firm/group and had above average calls with AN and VP in addition to a VP and an MD+ pulling for me (to at least get the first round). I've heard that networking is really only important to get first round, but considering that I'm not confident that I'll make it to the next round, should I update them about how everything went?
My next step: send interviewer thank you note and ask for feedback. Do I leave it there or Do I update my contacts before I get what will likely be a rejection? If so, what do I say? Thought process being that maybe they'll push for me before I get rejected. Or should I wait until after I get the rejection to update contacts and just thank them for their help getting an interview?
