Some background, we are a small Dutch tech startup of currently two people looking to expand with another engineer. This hire seems therefore quite crucial for us.
I just had an interview with a candidate, which I asked beforehand to send me a resume or a list of previous projects, which he did not have.
In the interview I got the impression, as much as you can tell from just a talk, that he knows what he is talking about engineering-wise. However, when I asked him again where he worked before, he said that he would rather not tell. Even after I tried to explain to him that it is going to be impossible for me to come to a positive conclusion without any employment-history or at least a good reason for not listing employment-history, he still did not want to give any.
For me this seems like he left some scorched earth at his previous projects, but could there be another valid explanation for this?
The applicant does not live in this country (but a neighboring one), so the interview was over Skype.
He doesn't have a CV, a LinkedIn profile, or a written employment-history.
He said that he mostly did freelance work. Presumably for multiple clients which he got by word-of-mouth referrals.
There seems to have been some confusion here over what I meant by "references". I was not asking for a reference person or a letter of reference. The question now talks about employment-history.
