This question is asked just for informational purposes and you should not base your decision solely on the answer to this question. Although tools play an important role, the tool match is not that important.

If your candidate knows one tool and not another, the chances are high that they will easily be able to pick up the different tools too. However, there are a few exceptions here.

If you are hiring a UI/UX designer for an urgent project and want them to work on a tool right from day one, do not expect a quick turnaround time here. Your designer will take their own time, depending on the learning curve of the tool, and their grasping power.

Thus, the know-how of your designer on the UX tools should not be a subject of concern if you are hiring them for long term product development.

However, if it is an urgent need, you should choose to hire someone who is already familiar with your preferred tools.
