So, I stated a salary range during an initial interview with a company. It was based on information extracted from 2 websites, where I found example salary ranges offered by this comany for similar roles. One website was stating higher ranges than the other. So, I kind of made an average of the 2, because I was worried that if I only take into account the website with the higher ranges, I may be overestimating. In contrast, if I consider the website with the lower ranges, I may be underestimating.
But let's say that I'm underestimating. If I am asked the salary expectation question again in a subsequent interview, what do I comment after stating the numbers? In the case of a potential overestimation, you can argue how you are good fit for the job and have the right experience and skillset in order to convince them. But I'm wondering what can be said in the opposite case.
I am asking this here as I am not experienced in this matter because I come from an academic job where the salaries are not negotiable.
Edit: I am not planning on mentioning a higher range in a subsequent interview. Just what to comment after stating the salary, such that I don't look like I'm underestimating.
Also, I wasn't given any feedback on the range I gave, probably because
the initial salary question is done as an "order of magnitude" sanity check
