“This part actually went fine.”
“This was one of the two that wrecked me.”
“I said something reasonable: coming from contracting, salary alone doesn't tell the whole story, and I'd need to understand the role better before throwing out a number.”
“Five minutes left on the clock and this is what they ask.”
“Said something like 'I concluded my time there a few weeks ago and I'm looking for the next opportunity.' Which, sure, technically true.”
“This is apparently what tanked me, which is wild because I was straightforward about it from day one.”
“I thought I had this one.”
“I put real time into this.”
“I'd actually prepared a one-pager before the onsite without being asked, so when this came up as the very first question I just slid it across the table.”
“I went deep.”
