During the tech interviews, how often do you ask a new question that wasn't a part of your existing question set but is relevant to evaluate candidates?
For me, the questions are not really pre-scripted, but based on the discussion and the candidate's relevant experience on the particular topic, the questions get's framed on the spot.
It depends on the scope of the role. For Sr. dev talent I have a tendency to skew more towards questions that arise during the long form interview. For more Jr. level devs / data scientists / UI/UX hires I try to stick to the question bank as best I can.
