Postdoc: internal v. external candidates. Can I expect a fair process? I have recently interviewed for a Postdoc position in a Scandinavian country, where the short-listed candidates have access to ranking and comments on how they were selected. I saw that the other person selected for the interview, already works there as a Researcher, probably on a temporary contract. Given the transparency of the process, I assume this would not matter much. However, it is human to be unconsciously biased and I have a fear that the professional intimacy shared by the candidate and members of the committee might not be in my favor. 

The interview was really nice, a positive experience where I felt I connected with the committee, smiles were exchanged and my overall gut-feeling was that I could get the job. I can't help thinking, however, that I might lose over this detail. 

Any thoughts and experiences?

EDIT: I do have another question, related to the selection process in Scandinavia: has anyone experienced a situation where 2 candidates are promising, and the PI or university opens another job or simply, they hire both? In my context, I know the PI has funding and could do this if they wanted. I wonder how common this is?
Nothing in life is certain, of course. Different places have different rules and different levels of actual adherence to the rules. Your concern that they may prefer a known quantity may well be balanced by their desire to bring in a fresh face. Different members of the search committee might have different preferences if they have any at all. 

But it sounds from what you write that you are likely in a fair process even if that isn't a universal phenomenon. 

But, in the end, they will choose the person who they feel is best for the position, based on whatever formal and informal criteria they have. You have no actual influence over that. 

I'd suggest that you take a deep breath and also have a backup.
