Pivoting your career can be construed as having failed somewhere and needing to find something else.
In the context of a career, phrase it as evolving your skills to match market demand. The very people who "pivot" resonate with will immediately associate it with failure.
Yes, it's an overused term but it's NOT a sign of failure.
For me this is not something negative at all
When interviewees are asked "So why are you looking to move from your present job?". Saying that you need a new challenge sounds very different than "needing to pivot".
However, interview gives one a very limited time to impress. Better use it to discuss your strength and the future, not invite archeological queries.
There isn't anything more concrete than that. YMMV. In this particular case, it rings true to me.
Independent of that, I think using the word 'pivot' here is fine. We all know what he means. There might be a different word with a different connotation that some people may be more receptive to. But, pivot is well within the realm of reasonable words to use here.
I tend to find such polemics unhelpful. Usually when someone tells me "just don't", I end up really wanting to know the mechanism behind what is causing such a stern warning.
For example, if I asked someone, "should I jump out of an airplane with no parachute",...
and someone says...
"just don't, because unless you have lots of luck and can defy lots of laws of physics, you will most likely be killed"...
then they have revealed a very clear and concrete reason, which strengthens their assertion of "just don't".
I see no such evidence for or against using the word "pivot", and I can imagine scenarios where the word even resonates with certain types of people.
