This question already has an answer here:
I recently attended two interviews for a position, a general ‘meet each other’' interview, and then a technical interview.
Both interviews seemed to go well, friendly and amicable. However, I was informed that while I was a good cultural fit, I didn't have the technical skills for the position (I don't have working experience with the technology they’re using, just what I've learnt in my spare time). They said to keep in touch if any positions come up.
The question is—would it be appropriate to add one of the interviewers on LinkedIn? Is this what LinkedIn is used for?
