I recently applied for an internship at a large company which had several software developer positions with very different job descriptions. During my interview, the topics discussed matched perfectly with the description for one of the software developer positions that I did not apply to.
Needless to say, I am concerned because this was not the interview I had prepared for, and this position did not match well with my skillset. Is this something they may have done intentionally because the position I originally applied to has already been filled, or was it most likely someone's mistake? Should I let them know, and if I do is there any chance I'd get a second interview or some other recourse?
Any and all advice is greatly appreciated.
