I checked this topic before asking this question. To me this is more of an ethical question. Last year I applied for a job and I couldn't get it due to lack of experience.
In the company's rejection email they told me to study more and apply again if you want (it was an auto email I guess but it said something like what I mentioned). I did so, I studied very hard for the past year and I applied for the job one more time.
Currently I passed 3 stage of hiring process and I'm going for the last one. Till now they didn't mention that I've interviewed here and they didn't question me about it either (I think they don't keep track of their candidates). I didn't mention it too.
Now I'm a bit worry about it, should I tell them about the last time? I believe that I improved a lot and I don't want them to judge me by last interview results in other hand I don't want risk loosing this opportunity due to lack of honesty.
I should also mention that this time I applied for another branch in another city, I mean same company, different branch. The company located in Netherlands.
