Forgive a painful mixing of metaphors: if the Workplace StackExchange is anything to go by, one interviewer's flying colours are often another interviewer's red flags.
This is absolutely true.
In /r/RecruitingHell, I recently saw a job seeker saying a hiring manager dropped them after they tried to connect on LinkedIn during the interview loop. Meanwhile, another HM in another loop praised them for it.
Yup.
There's a fine line between giving a thorough answer and just vomiting up everything you know that's slightly relevant to the original question.
I do AppSec. If I'm interviewing a candidate, and I ask them what Cross-site Scripting is, then if at some point during their answer they bring up SQL Injection, that's a red flag.
